No it isn't: x4D is simply "M", not "ESC M".

ESC is a C0 control character and as such is not a legal XML character, so
you can't produce it in XSLT output. You'll have to find a different
approach, e.g. output a processing instruction
 <?ESC M?> and write a ContentHandler to convert this at serialization time.
