It's not possible to "fix" this - it isn't even broken. The *db modules, by design, support storing of arbitrary bytes, not just character data. You can put images into them, or sound files, java byte code files, etc. So if Python would assume they have to be UTF-8 encoded character strings, it would severely limit the usability of these modules. For keys, things are slightly different from values - there is a higher chance that the keys are indeed intended to be character strings. However, in the bsddb btree format, any byte sequence that has a good lexical order can be used as a key, and people do use the interface that way (e.g. by putting an md-5 hash as the key, and the original data as the value). It would be possible to put a layer on top of them which assumes that either keys, values, or both are characters, and that they are further UTF-8 encoded. However, such a package doesn't need to be part of the standard library. Regards, Martin -- http://mail.python.org/mailman/listinfo/python-list
