Ezio Melotti <ezio.melo...@gmail.com> added the comment: I can't reproduce it either on Ubuntu 9.04 32-bit. I tried both from the terminal and from the file, using Py3.2a0.
As Martin said, the fact that in narrow builds of Python the codepoints outside the BMP are represented with two surrogate pairs is a known "issue". This is how UTF-16 works, even if it has some problematic side-effects. In your example 'line[0]' is not equal to 'first' because line[0] is the codepoint of the first surrogate and 'first' is a scalar value that represents the SHAVIAN LETTER TOT (U+010451). Regarding the traceback you pasted in the first post, have you used print('𐑑') or print(line[0])? This is what I get using line[0]: >>> line = '𐑑𐑧𐑕𐑑𐑦𐑙' >>> first = '𐑑' >>> print(line[0]) Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'utf-8' codec can't encode character '\ud801' in position 0: surrogates not allowed In this case you are getting an error because lone surrogates are invalid and they can't be encoded. If you use line[:2] instead it works because it takes both the surrogates: >>> print(line[0:2]) 𐑑 >>> first == line[0:2] True If you really got that error with print('𐑛'), then #3297 could be related. Can you also try this and see what it prints? >>> import sys >>> sys.maxunicode ---------- nosy: +ezio.melotti priority: -> normal _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7045> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
