for these wowels pairs, this is not impossible to do: but one must remember that ya, yo, yu are in fact compound letters (even if they are composed in the johab set of jamos that was used in Unicode) and are safely decomposable in Hangul as separate vowels, even if they are not canonically decomposable in Unicode. So you could safely decompose, when creating the document, these compound vowels, so that they can be each assigned a distinct style for instructing renderers. It's just a shame that these compund letters were not given explicit canonical decompositions in Unicode (so that they would not occur with documents in NFD and NFKD forms, but could still be compressed with johab compound jamos and then as LV and LVT syllables in NFC and NFKC forms). As a rendering process such as a browser does not need to output characters when rendering Hangul texts, I think they can safely add these decompositions internally and recompose to NFC form to optimize the final rendering in fonts, when the letters in the same syllabic cluster share the same style; if this is not the case, then it's up to the browser to split syllables and render them using more basic Hangul jamos (but then the browser needs to know the way multiple jamos are composed, i.e. <L*V*> above <T*>, then <L*> on the left of <V*> unless <V*> is horizontal (in which case <L*> is above <T*>, and then letters in <L*> aligned horizontally if they are vertical, such as SSANG* CHOSEONG's), and same thing for <V*> (this includes the vowels pair YE which is composed horizontally, as Y is vertical). The Hangul script is so logical that even complex clusters are easy to compose and read, and even to transcode to ASCII or to sort. __________________________________________________________________ << ella for Spam Control >> has removed Spam messages and set aside Newsletters for me You can use it too - and it's FREE! http://www.ellaforspam.com
