This is in fact the behavior of many Thai systems (computer fonts, typewriters, etc.), but I think that it has to be seen as a approximation, rather than as the rule. In good typography, Thai tone marks should normally be at the same height as top vowel marks, when they apply on a letter with no vowel marks, and slightly higher when they stack on top of a letter which already has a vowel mark on top. This is supported by the fact that "glyph-encoded" fonts often have two version of tone marks, at different heights. I also noticed that some Thai fonts contain precomposed combinations of vowel marks + top tone marks. These combinations sometime present some form of ligature between the two marks (ad-hoc position or size; overlaying), rather than simply stacking them on top of each other. I should still have these fonts somewhere, in case you need examples. _ Marco --- + --- + --- + --- + --- + --- + --- + --- + --- + --- Prego di notare che il mio indirizzo di e-mail � ora: [EMAIL PROTECTED] Il mio vecchio indirizzo verr� chiuso fra pochi giorni.
