Do you mean saving two characters for posting to Tweeter ? Well may be, but Tweeter clearly does not promote correct typography and not even correct orthography. It is clearly not a good model for publishing.
But given the history of this character, I just wonder why it was not mapped along with East-Asian compatibility punctuations where it should have always been. And many fonts have ignored this history and the intent for compatibility with legacy CJK codepages. So not only they used incorrect metrics for use with other scripts, but they also did not honor the metrics of these CJK scripts. This is now a character which we should not use at all as it does not even work as intended in any context (except for those similar to tweets). If there's something to do now (given it is no longer used in CJK contexts), it's to strongly recommand that fonts map them to exactly the same glyph as the one obtained by aligning three periods in a raw without any additional space or kerning. And may be demand that renderers ignore these font mappings and systematically replace it with three separate periods so that they can properly apply correct justifications and glyph metrics, with at least two branches depending on the previous glyph (CJK or not, and possibly: if CJK, half-width or fullwidth, otherwise look at font metrics of the previous glyph to see if it's monospaced or not and if not, replacing by using 3 standard periods). Those users that will want more spacing between dots of an ellipsis should have to use explicit spacing in their encoded texts. And those that want less spacing should use ligature control such as ZWJ between standard periods as well Clearly this character must be clearly deprecated for all uses except CK contexts, and should probably be even dropped from mappings in most fonts (except CJK or monospaced fonts). 2013/9/15 Andre Schappo <a.scha...@lboro.ac.uk> > > On 13 Sep 2013, at 20:02, Whistler, Ken wrote: > > > The *interesting* question, in my opinion, is why folks feel impelled to > use > U+2026 to render a baseline ellipsis in Latin typography at all, rather > than > just using U+002E ad libitum... > > --Ken > > > U+2026 is useful for microblogs when one is looking to save characters > > André > > >
