Further, percent-encoding neither in IRIs nor in URIs requires the
use of the UTF-8 encoding, it is very well possible that your
percent-encoding library uses ISO-8859-1 resulting in Slug headers
that cannot be decoded.
Yes. So, I think that we should decide encodings and character set
that can surely be recognized by all APP servers.
Sorry, I don't know the situation in Germany, do you have two major
encodings, iso-8859-1 and utf-8?
If the encoding that should be recognized by all APP servers is
assumed to be utf-8 like XML, I think it is good for interoperability.
Anyway, this issue is unrelated to percent-encodings.
