escape = "%" hex hex
Judging from the fact the "~" is legal (and used) in URLs and "[" and
"]" are also listed under "national" I'd say that Rails use of those
characters (unescaped) is probably just fine for most cases. Although
they are not listed under "safe" so there might be some obscure edge
cases that might present an issue. But, I doubt there's any reason to
worry about it.
