I've got an binascii.Error as the attached file. What I did was to get this error is the following. 1. Adding to a user folder a 'New User' whose id is composed of non-ascii characters. And there were no errors(this is true when I did the same to a user db). 2. Trying to access manage page as that 'New User' What I can see from the source code is 'v'(=validate) in User.py line 388 calls python builtin module base64. And since base64 is 'built-in' and I'm an awfull newbie, I can not guess what is v, decodestring, and base64 do(Obviously, 'v' get name & password for authentication). Ansorry situation. I wish Guido had implemented base64 in python not in C. .... So if anybody knows what v does with what kind of data reveal his sacred knowledge, I'd like to write a python bits to solve this problem(for those with non-ascii character names). I suggest this will be the 1st step for internalization of Zope(though only two guy from Chech & France and me seems interested in that). Quite weeks ago, I did some ugly hack to circumvent a id checking method to be able to add object whose id is composed of non-ascii characters. For IE and Netscape Korean version, there was no problem with that hack. But now I abandoned it, 'cause it's non-standard to use non-ascii chars in URL(very sorry situation though :(. But user's name is not a object id but a part of qurry string. So it seems(at least to me) not a violation of the standard. Being able to type in one's own name in his or her own language is very^3 user-friendly, don't you think so? for Zopal revelation, LEE Kwan Soo.
