Or we could have a function that recreates the dictionary from the string. Actually, I'd prefer that these operations be done by the codec generator script, so that we don't have additional startup time. The dictionaries should then no longer be generated and instead. I'd like the comments to stay, though. This can be done like this (using string concatenation applied by the compiler): decodingcharmap = ( u'x' # 0x0000 -> 0x0078 LATIN SMALL LETTER X u'y' # 0x0001 -> 0x0079 LATIN SMALL LETTER Y ... )

I'd prefer that too.

Either way, monkey patching the codec won't work anymore. Doesn't really matter, though, as this was never officially supported.

We've always told people to write their own codecs if they need to modify an existing one and then hook it into the system using either a new codec search function or by adding an appropriate alias.

OK, so can someone update gencodec.py and recreate the charmap codecs?

BTW, is codecs.make_encoding_map part of the official API, or can we change it to expect a string instead of a dictionary?

Bye, Walter Dörwald
