[PD-dev] [not trivial] escaping special character in messages

[Krzysztof Czaja]

hi Nicola,

no easy way... you could force commas and semicolons into message
boxes with something like '44' -> [makefilename %c] -> 'set $1' ->
'', but they would not survive saving into a .pd file.  So perhaps
you would rather prepend a [loadbang] to '44', and make your patch
construct the message while loading.

Btw, this is not a trivial question -- the escaping thing is quite
complicated in Pd.  For example. a backslash in '\,' would need to
be escaped itself in a .pd file, like '\\,'.  I vaguely recall
a thread on pd-list about how to enable escaping and/or quoting
by the user.  I think the proper escaping or quoting mechanism
waits on a todo list...
