--- Comment #2 from Stefan Zipproth <stefan.zipproth at web.de> 2014-02-25 00:56:32 PST ---
RFC 3986 states in section 2.1. Percent-Encoding

   For example, "%20" is the percent-encoding for the binary octet
   "00100000" (ABNF: %x20), which in US-ASCII corresponds to the space
   character (SP).

So UTF-8 is not the standard used for URI percent encoding. Therefore,
std.uri.decode should not throw an exception if its parameter contains %E4. It
is allowed for browsers to encode German umlaut ä as %E4, which was the reason
I ran into this problem (because my server side application crashed as soon as
std.uri.decode was called).
