Well, I tried it with: a) the Vietnamese "tonal marks": - grave U+0300 combining class: 230 - hook above U+0309 combining class: 230 - tilde U+0303 combining class: 230 - acute U+0301 combining class: 230 - dot below U+0323 combining class: 220 b) the Vietnamese "modifier" characters: - breve U+0306 combining class: 230 - circumflex U+0302 combining class: 230 - horn U+031B combining class: 216 I tried to combine them with the space character and with some vowels. The tonal marks went usually quite fine, but the modifier characters did not: In WinME, they did not work in MSWindows97, OpenOffice641. In IE5.5 they did not work with the space, and only with the "right combination" of vowels and modifiers: OK: (all vowels a,e,i,o,u) + (any of breve or circumflex) OK: o + horn, u + horn (which are in fact valid Vietnamese characters) NOT OK: a + horn, e + horn, i + horn (which actually are not valid Vietnamese characters) Are the described issues a problem of the OS (e.g. rendering engine), application (why does IE behave different from Word?), or correct Unicode implementation (e.g. that the horn does not combine with a,e,i)?
