[cl-ppcre-devel] Fwd: string length limit ?

Sorry if this is a trivial issue, I'm a common lisp newbie.

If I apply the following very simple command (replacing one or more consecutive CR chars with one LF char)

(cl-ppcre:regex-replace-all (concatenate 'string (string #\return) "+") mystring (string #\linefeed))

to my string of 455079 characters (loaded from a utf-8 file), some of the last #\return characters are not substituted (even if they should, since if a apply again the command to the resulting string they ARE subsituted). It looks like in the search there is a sort of length limit, or maybe some string length mistake connected to multi-byte characters representation ?

Cheers.
