You still don't undestand: I want the composite to behave as if it was a letter that is missing and it is supposed to replace (including in the middle of a word... There's no attempt to insert a line break (in fact I don't want it before or after, unless there are breaking characters around such as punctuation or spaces).
You attempt to explain me things that I already know, but this is not the subject my question. Clearly your suggestion of NBSP was wrong for my request. SHY+diacritic would be correct in Latin/Greek/Cyrillic, but not in Korean, and it would add an undesired break oppostunity (note like a standard letter with the sme diacritic) I expect that the placeholder rendered will discard the control but want it to render the glyph appropriate for the placeholder needed for defective nd ill-formed combining sequences, chosen ccording to the first diacritic. after the control (or their ligature if there are several diacritics). 2013/10/21 Richard Wordingham <[email protected]> > On Mon, 21 Oct 2013 13:34:56 +0200 > Philippe Verdy <[email protected]> wrote: > > > > On Mon, 21 Oct 2013 01:41:12 +0200 > > > Philippe Verdy <[email protected]> wrote: > > > > > Is there standard way in Unicode to specify tht one wants to > > > > display a combining > > > > mark in isolation ? > > .... > > > I would have prefered tht you answer WORD JOINER+diacritic.
