Hasn't the URI spec recently been updated to both follow already common practice and define the encoding to be used? (I've just remotely followed this.) See e.g.: <http://www.gbiv.com/protocols/uri/rfc/rfc3986.html#percent-encoding> (last paragraph of Section 2.5; I'm aware that this is a general URI definition document, not explicitly applying to existing protocols like mailto: ) So, the recommendation is to encode any non-ASCII characters first as UTF-8, then encode that octet (byte) sequence using "%" hex escapes. So effectively, the encoding has been fixed at UTF-8. An 'ü' would therefore be encoded like this: ü = Unicode: 0xFC = UTF-8: 0xC3 0xBC = URL: %C3%BC (At least this is what I am doing with URLs with hi-ASCII characters in my own product.)
