Hi,

Mathematica need a double back slash "\\" for a true back slash,
because it use \ in combinations for control codes "\n" for new line,
"\t" for a tabulator.
But there is not really a problem
StringReplace["$\\tau\\,\sin(\\xi \\pi)$", "\\tau" -> "tan(\\psi)"]
work as it should.

Regards
   Jens
