I've been thinking the problem is lack of % encoding after reading: *"Default encoding for GET* The character set for HTTP query strings (that's the technical term for 'GET parameters') can be found in sections 2 and 2.1 the "URI Syntax" specification. The character set is defined to be US-ASCII <http://en.wikipedia.org/wiki/ASCII>. Any character that does not map to US-ASCII must be encoded in some way. Section 2.1 of the URI Syntax specification says that characters outside of US-ASCII must be encoded using % escape sequences: each character is encoded as a literal % followed by the two hexadecimal codes which indicate its character code. Thus, a (US-ASCII character code 97 = 0x61) is equivalent to %61. There *is no default encoding for URIs* specified anywhere, which is why there is a lot of confusion when it comes to decoding these values. " from http://wiki.apache.org/tomcat/FAQ/CharacterEncoding#Q8 Do you know if there's a way to force something (mod_jk, mod_rewrite or something else) to % encode the data being fed into the AJP port?
