There are a couple of implementations of urldecode.
One in the filter, another one on z_url.
And probably a third one in webmachine/mochiweb.
Url encode might have multiple incarnations as well.
We should check if we can replace these functions with http_uri:encode/decode.
http_uri is R15+ only.
I think we should track the Erlang release of Linux distributions.
Ubuntu 12.04 LTS is on R14B04, so imho we should stick with R14 until there is a new LTS release.
Agree, but just ignore Debian - that one is ancient.
Debian testing (wheezy) is actually on R15B1...
http_uri:encode and decode are available in R14 too.
