I'm using the fragment identifier to create a permalink for AJAX events in my web app similar to this guy. Something like:
http://www.myapp.com/calendar#filter:year/2010/month/5
I've done quite a bit of searching but can't find a list of valid characters for the fragment idenitifer. The W3C spec doesn't offer anything.
Do I need to encode the characters the same as the URL in has in general?
There doesn't seem to be any good information on this anywhere.
See the RFC 3986.
fragment = *( pchar / "/" / "?" )
pchar = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded = "%" HEXDIG HEXDIG
sub-delims = "!" / "$" / "&" / "'" / "(" / ")"
/ "*" / "+" / "," / ";" / "="
So you can use !
