Thread:Project:Support desk/Encoding problems in Table of Contents links/reply

I think that I also saw this issue on Wikipedia - I am not sure, if there is a "fix" for this. MediaWiki is encoding the signs inside the URLs according to I don't know what standard. RFC 3986 (see Section 2: Characters) contains the according rules. Valid signs for URLs are:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789-._~:/?#[]@!$&'*+,;=

All other characters need to be encoded.
