Hi Jan,

Of course (not having looked at the patch in any detail) one question
is how you (want to) deal with non-printable characters (potentially
encode-able via backslash escapes),

The patch currently does not support escape sequences, except for anescaped double quote. Perhaps it should.

since some are being used by
gas internally (on the assumption that user provided symbol names
can't contain them).

Currently only two values are used by gas internally - 0x1 and 0x2.Assuming that escape sequences were enabled we could add a check andcomplain if either of these values were used. Or just allow them andwarn the user that they really need to know what they are doing.


Cheers
  Nick
