= What does this `UnicodeEncodeError` mean? = It means that a given `unicode` object (i.e. the Python internal representation for a sequence of internationalized characters conforming to the Unicode standard) failed to be converted to a `str` object (i.e. a sequence of bytes). The failure means that there was a character which couldn't be represented by an appropriate sequence of bytes in the chosen output encoding. In practice, the default conversion being a "strict" one using the default encoding, which is 'ascii' most of the time, the error will happen as soon as the `unicode` object contains characters outside of the ASCII range of characters (codepoint 0 to 127). This error was frequently seen during the transition to internal use of `unicode` that happened in Trac [milestone:0.10], and can still be seen now and then with Trac plugins that are not using the Trac API the way they should. Examples: {{{ >>> str(u'chaîne de caractères') Traceback (most recent call last): File "<stdin>", line 1, in ? UnicodeEncodeError: 'ascii' codec can't encode character u'\xee' in position 3: ordinal not in range(128) >>> }}} The above is actually equivalent to the following, as `sys.getdefaultencoding()` is frequently 'ascii': {{{ >>> u'chaîne de caractères'.encode('ascii') Traceback (most recent call last): File "<stdin>", line 1, in ? UnicodeEncodeError: 'ascii' codec can't encode character u'\xee' in position 3: ordinal not in range(128) }}} One possibility to force the conversion to happen would be to use a non-strict conversion: {{{ >>> u'chaîne de caractères'.encode('ascii', 'ignore') 'chane de caractres' >>> u'chaîne de caractères'.encode('ascii', 'replace') 'cha?ne de caract?res' }}} ---- See also: TracDev/UnicodeGuidelines, UnicodeDecodeError
