At first sight from what I quickly tried to do with escaped double quotes
(\") in the regsub() function I would think you're right and there's a bug
there.
There may be something going on with GLib versions here. On Linux with
GLib 2.44.0 the following works fine:
<hansl>
string s1 = sprintf("string with \"quoted\" bit")
print s1
string s2 = regsub(s1, "\"", "*")
print s2
</hansl>
<output>
? string s1 = sprintf("string with \"quoted\" bit")
Generated string s1
? print s1
string with "quoted" bit
? string s2 = regsub(s1, "\"", "*")
Generated string s2
? print s2
string with *quoted* bit
</output>
