You seem to be suggesting LO remove its font selection dialog, or the font selection pane of the font dialog, entirely... Font selection belongs in (almost) any application in which the user needs to select fonts. And while complex font exploration may perhaps be better suited for a different app, it is not a complex or esoteric task to want to choose a font which can be used for the language you want to write in; and my office productivity app must help me avoid choosing fonts (or font families) which don't cover the language I'm making the choice for. > It has *ALL* the features that Eyal is asking for, I asked for just one thing. And I'm not even the one who asks for it; I would argue every user asks for it: Not misdirected into choosing an invalid font for the language I'm writing in. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=151122 --- Comment #13 from Heiko Tietze --- What bothers is the wish to get some very broad information at a control that is simply a picker. But if we turn it around and show incongruencies it makes sense. We draw the font name in italic if not available on the system and could so something similar if the listed font item unicode coverage does not match the paragraph language. -- You are receiving this mail because: You are the assignee for the bug.

https://bugs.documentfoundation.org/show_bug.cgi?id=151122 --- Comment #12 from Eyal Rozenberg --- (In reply to Telesto from comment #10) > You ask yourself, does the Hebrew font cover the same characters as the > Western font.. Now I get it :-). Oh, you made the wrong mistake :-P First of all - that's meaningless. There's no need for the font used for Arabic (not Hebrew, the screenshots has Arabic sample text despite Hebrew being selected as the language which is another bug I should file I think) to cover the same characters as the one of Western scripts. In fact, they might as well be disjoint. I was expecting you to say "the three fonts look almost similar in Arabic" In fact, _none_ of the three fonts in the screenshots supports Arabic, or Hebrew, at all. It only looks like they do, and it even looks like the three fonts are slightly different - as apparently somehow the glyph spacing is taken from the font's general meta-data, so the result doesn't look the same. If you choose one of these fonts for CTL, you'll just get some fallback font glyphs used, and you would not be told which font (family) those fallback glyphs are taken from. This is a problem for people, because: * The user believes a certain font supports Arabic, while it doesn't. * If the user sends this file to another person, that other person is likely to see it rendered differently - depending on which OS, VCL and font choices they have, which in turn determines the fallback font used. * The chosen font may cover one CTL language's range of glyphs but not another one's. Even if the preview corresponded to the chosen language - how would the user choose a font which has glyphs for both, say, Hebrew and Arabic? Or Arabic and Shahmukhi (Punjabi)? The third problem affects fewer people - but still, quite a few. The first two problems are faced by RTL/CTL users all the time. In fact, all three problems affect even people who only use LTR/Western languages, as in the example I gave with Cyrillic, above. -- You are receiving this mail because: You are the assignee for the bug.

Like MSO? It is not, nor should it be. And that is the issue. There are already some fabulous programs for doing font selection based on its Unicode coverage.

https://bugs.documentfoundation.org/show_bug.cgi?id=151122 --- Comment #8 from Telesto --- @Eyal You're clearly wanting to achieve something and struggling with fonts/ font replacement. I haven't taken much interest in fonts (or font family's etc). I'm only aware of font substitution because I encountered documents on the bug tracker with exotic fonts. (And couple of layout bugs caused by font substitution). So I really lack the understanding of the whole topic.. Would you mind to share what you're working on (some integral for all recent reports). And what the issues are you're encountering. It sounds highly specific what you want to do from a distance. And those requests are highly technical .. I lack knowledge of limitations of fonts (how many symbols each font supports). And I have surely no clue about font issues with Hebrew/Arabic/Chinese/Japanese fonts (and font family's). -- You are receiving this mail because: You are the assignee for the bug.

A font selection dialog (FSD; versus, say, a font choice text box elsewhere in the UI) is not intended merely for the user to communicate their apriori choice of font - but rather to allow the user to make the choice while in the dialog. While its true that this dialog is not a full-fledged "font explorer" - it does presume to allow making that choice - via the preview area. The idea is that you see what the font looks like for some piece of text, and make your decision. But this has two underlying assumptions: 1. That the font you see in the preview area is the actual font you're selecting (rather than some kind of fallback). 2. (When assumption 1 holds) That if the font covers the glyphs used for the preview area, then it covers all glyphs for all of the languages in that language group you intended to use. (*) These assumptions almost always hold if you're writing English, and usually hold if you're writing German or other Latin-based alphabets. But that is absolutely not the case for other languages, especially in CTL language-group. Let's ignore CTL for a second though. Suppose I want write in Russian. Some fonts have glyphs for the Cyrillic alphabet, some don't. I cannot choose from amongst a set of fonts unless I know that they are fonts which cover all glyphs related to the Russian language; and the font dialog does not let me know that this is the case. You both seem to suggest that I should first open the SCD and check. That is a weird suggestion even if it were valid - to use a not-directly-linked dialog, from another menu, which officially has an entirely different purpose, as part of the font selection process. But even ignoring its weirdness - I can't use the SCD to choose between fonts, since I don't see how a stretch of text looks in a given font; and I can't use the FSD to choose between fonts since a great many of the fonts I'm offered I can't actually use. And I also cant use the FSD since the stretch of text presented in the preview is not in my language of interest. (Yes, I can first type some text in Russian, then select it, then launch the FSD, and I'll get the preview I want, but that's cumbersome and newbie users won't even think of doing that. And there's the fact that the preview might not actually use the font itself but some fallback.) So even by LO's current effective standard of what's necessary for selecting a font, this information needs to be related somehow. In fact, _some_ of it is already related - by placing some fonts in the Western language-family list and other fonts in the CTL language-family list: That's a partial indication of which parts of the Unicode plane are covered by the font family. What is necessary is additional refinement - somehow - to let the user choose only from amongst the fonts relevant to the languages they intend to write in. Stuart worries about avoiding UI garbage. I agree that this is a danger and that careful thought is necessary. But something needs to be done, and users cannot be expected to do trial-and-error font selection. So how about we focus on my first possible idea: * Filtering the list of fonts by the choice of language already present underneath the list: Only those fonts offering all glyphs associated with the chosen language will be displayed. * (Possibly) allowing the choice of multiple languages in the widget(s) below the font list, for stricter filtering. > If necessary a special dialog perhaps realized via extension > could give insights to font attributes. If something is necessary, then it needs to be in LO itself. If it's nice-to-have it may belong in an extension. I hope I've managed to convince that LO's own "standard" for what's necessary for font selection also necessitates some UI change to avoid mistaken selection of language-incompatible fonts. -- You are receiving this mail because: You are the assignee for the bug.

The Special Character Dialog (SCD) is where LibreOffice's delivery of these Unicode font coverage issues belong. I'd also argue that detailing font fall back and even font replacement (the Tools -> Options -> Fonts panels) likewise need linkage from the SCD. Attempting to provide such details via the font selection listboxes (e.g. with tolltip and pop-up dialogs) is recipe for UI garbage. And is a "Horrible idea". When you are assigning the font is not the time (or place in the UI) to be identifying the font to use. -- You are receiving this mail because: You are the assignee for the bug.

Hmm, yes, that's true, that dialog doesn't show the silly fallback text. But it's very inconvenient for someone to have to go back and forth between the two dialogs, to check. Possible ways to get this indication: * Filter the language-family font-family-list by chosen language and features. * Sub-option: Same, but allow requiring multiple languages. * Stylistic indication of which fonts in the language-family font-family list support the chosen language. * Have some button or hover-over-able widget open up a list, perhaps bulleted by symbolic icons, of the BMP regions covered by the font family. i.e. essentially the same list from the Insert Special Character dialog. Orthogonally to the above: * Add ability to toggle the fallback font use in the preview area of the font selection dialog, on or off. -- You are receiving this mail because: You are the assignee for the bug.
