I will look into all of that, and thank you for it; but note that of those only Thaana can be expected to display, as none of the others have been encoded. So none of those could EVER be displayed; they are just extra glyphs in the current font. Syloti Nagri has been approved by UTC and assigned to A800..A82F, though this is yet to be ratified by WG2 (presumably will happen in October) and published in a new version of Unicode (will be 4.1) or an amendment to ISO 10646 (I don't know what timetable is in place for publishing further amendments).

Does this Generate glyphs like the following ascii- utf8-art? No. It generates much much better glyphs than that.

More useful if you are trying to debug why, in a span of Arabic text, some characters aren't being located in a font? Not really. I find it interesting, if so, that Apple uses a font to acheive that rather than a bit of code in the rendering libs. What Mac OS X does is when it encounters a Unicode character, it sees if it's in the current font. If it's not, it starts looking through all the other fonts until it finds one that is suitable. The Last Resort Font has glyphs for all the characters, so it's the last one looked at. If you have a Last Resort style font, Pango should pick it up as well (*). The hex boxes are only drawn when *no* font on the system contains the character. Regards, Owen (*) With some caveats about fontconfig configuration that I'm not going to get into here.

More useful if you are trying to debug why, in a span of Arabic text, some characters aren't being located in a font? Not really. The glyph (if you look at it zoomed in enough) tells you the block the character is encoded in. It doesn't tell you WHICH character isn't in any usable font.

The system looks for Unicode glyphs in all the other fonts and if there's no available glyph the the LRF is displayed. It's the last resort. There are, of course, some lovely easter-eggs in the font -- Michael Everson * * Everson Typography * * http://www.evertype.com

I don't know what Pango is but I guess it isn't relevant to me... It was mentioned in the mail that you replied to (because of it's hex-box-drawing) so I didn't feel a need to gloss. Pango is an text layout library roughly along the lines of Uniscribe/ATSUI/etc, developed largely by myself, with lots of help from the open-source community, including various people on this list. See http://www.pango.org for really outdated content. (Not much time to update the web page these days.) If you don't use Linux or Unix, it's likely not relevant to you. It's used pretty widely these days in that arena. Regards, Owen
