[docs] [issue18572] Remove redundant note about surrogates in string escape doc

Ezio Melotti added the comment: I think it's OK to remove the sentence. Converting a surrogate pair to a non-BMP char is something that works only while decoding a UTF-16 byte sequence. Surrogates are invalid in UTF-8/32, and while dealing with Unicode strings, surrogates have no special meaning and are no different from any other codepoint, whether they are lone or paired. ---------- nosy: +ezio.melotti _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue18572> _______________________________________
