I used the term glyph because I was talking about what the user is doing with text as presented to him by his U/I.  I'm fine with using the character here.

In short, I asked: if the user replaces X with Y (at the presentation layer) is it okay to send, instead of sending "replace the code points of X with the code points of Y", the minimal change in the underlying code points (as they appear at the XMPP level), e.g. send "insert combining character Z".  I was mostly concerned about sending combining character without all the code point(s) they are intended to be combined with, possibly leading to inappropriate combining with code points of the markup.
