Just a dumb question, but since Koha is multilingual and filtering on UTF8
chars does not really sound asking too much ?
Why dont we use encodeURIComponent on the header string and call
url_decode_utf8 on the receiving side?

This could be kind of a convention for x-koha headers? Search for percent
encoding, evaluate results of decoding? And be done quite early in the process
on a general level when processing (PSGI) headers?
