   This works fine for me.

   This does not, since it is logically wrong.
   The text characters have no meaning in math mode;
   i.e., they do not exist in the font for the
   usual math-italics of variable names.

I get log messages as follows:

LaTeX Warning: Command \textfishhookr invalid in math mode on input line 1.
LaTeX Warning: Command \textglotstop invalid in math mode on input line 1.
LaTeX Warning: Command \textscripta invalid in math mode on input line 1.
LaTeX Warning: Command \textrevglotstop invalid in math mode on input line 1.
LaTeX Warning: Command \textsci invalid in math mode on input line 1.
LaTeX Warning: Command \textopeno invalid in math mode on input line 1.
LaTeX Warning: Command \textepsilon invalid in math mode on input line 1.
LaTeX Warning: Command \textturnv invalid in math mode on input line 1.


Missing character: There is no ɾ in font cmmi10!
Missing character: There is no ʔ in font cmmi10!
Missing character: There is no ɑ in font cmmi10!
Missing character: There is no ʕ in font cmmi10!
Missing character: There is no ɪ in font cmmi10!
Missing character: There is no ɔ in font cmmi10!
Missing character: There is no ɛ in font cmmi10!
Missing character: There is no ʌ in font cmmi10!

Changing this, so that these and other TIPA characters
are recognised in math-mode, would require a fair bit
of work to get right and be safe.


Attached is the version of Xunicode.sty  that I'm using.
Please compare it with what you have.
