[Message part 1 (text/plain, inline)]

Hi,

There are two bugs in the current uri-encode procedure in (web
uri).

Firstly, if you have an octet less than 16 it only gets encoded to %
HEXDIGIT instead of % HEXDIGIT HEXDIGIT.

scheme@(guile−user)> (uri-encode "foo\nbar")
$30 = "foo%abar"

Secondly, if you have a string with no unreserved characters, nothing
gets encoded.
scheme@(guile−user)> (uri-encode "<>\\^")
$31 = "<>\\∧"
scheme@(guile−user)> (uri-encode "<>\\^a")
$32 = "%3c%3e%5c%5ea"

Patches attached. Cheers,
