<a href="" class="RktModLink" data-pltdoc="x"><span class="RktSym">net/uri-codec</span></a> module
provides utilities for encoding and decoding strings using the URI
encoding rules given in RFC 2396 [<a href="doc-bibliography.html#%28cite._.R.F.C2396%29" data-pltdoc="x">RFC2396</a>], and to encode and
decode name/value pairs using the
<span class="stt">application/x-www-form-urlencoded</span> mimetype given the in HTML 4.0
specification. There are minor differences between the two encodings.</div></p><p>The URI encoding uses allows a few characters to be represented as-is:
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">a</span><span class="hspace"></span></span> through <span class="RktInBG"><span class="hspace"></span><span class="RktIn">z</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">A</span><span class="hspace"></span></span> through <span class="RktInBG"><span class="hspace"></span><span class="RktIn">Z</span><span class="hspace"></span></span>,

<span class="RktInBG"><span class="hspace"></span><span class="RktIn">!</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">~</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">*</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">'</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">(</span><span class="hspace"></span></span> and
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">)</span><span class="hspace"></span></span>. The remaining characters are encoded as
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">%</span><span class="hspace"></span></span><span class="sroman">‹<span style="font-style: italic">xx</span>›</span>, where <span class="sroman">‹<span style="font-style: italic">xx</span>›</span> is the two-character hex
representation of the integer value of the character (where the
mapping character–integer is determined by US-ASCII if the integer is
less than 128).</p><p>The encoding, in line with RFC 2396’s recommendation, represents a
character as-is, if possible. The decoding allows any characters
to be represented by their hex values, and allows characters to be
incorrectly represented as-is. The library provides “unreserved”
encoders that encode <span class="RktInBG"><span class="hspace"></span><span class="RktIn">!</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">*</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">'</span><span class="hspace"></span></span>,
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">(</span><span class="hspace"></span></span>, and <span class="RktInBG"><span class="hspace"></span><span class="RktIn">)</span><span class="hspace"></span></span> using their hex representation,
which is not recommended by RFC 2396 but avoids problems with some
contexts.</p><p>The rules for the <span class="stt">application/x-www-form-urlencoded</span> mimetype
given in the HTML 4.0 spec are:</p><ul><li><p>Control names and values are escaped. Space characters are
replaced by <span class="RktInBG"><span class="hspace"></span><span class="RktIn">+</span><span class="hspace"></span></span>, and then reserved characters are escaped as
described in RFC 1738, section 2.2: Non-alphanumeric characters are
replaced by <span class="RktInBG"><span class="hspace"></span><span class="RktIn">%</span><span class="hspace"></span></span><span class="sroman">‹<span style="font-style: italic">xx</span>›</span> representing the ASCII code of
the character. Line breaks are represented as CRLF pairs:
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">%0D%0A</span><span class="hspace"></span></span>. Note that RFC 2396 supersedes RFC 1738
[<a href="doc-bibliography.html#%28cite._.R.F.C1738%29" data-pltdoc="x">RFC1738</a>].</p></li><li><p>The control names/values are listed in the order they appear
in the document. The name is separated from the value by <span class="RktInBG"><span class="hspace"></span><span class="RktIn">=</span><span class="hspace"></span></span>
and name/value pairs are separated from each other by either
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">;</span><span class="hspace"></span></span> or <span class="RktInBG"><span class="hspace"></span><span class="RktIn">&</span><span class="hspace"></span></span>. When encoding, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">;</span><span class="hspace"></span></span> is used as
the separator by default. When decoding, both <span class="RktInBG"><span class="hspace"></span><span class="RktIn">;</span><span class="hspace"></span></span> and
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">&</span><span class="hspace"></span></span> are parsed as separators by default.</p></li></ul><p>These <span class="stt">application/x-www-form-urlencoded</span> rules differs slightly from the straight encoding in RFC 2396 in
that <span class="RktInBG"><span class="hspace"></span><span class="RktIn">+</span><span class="hspace"></span></span> is allowed, and it represents a space. The
<a href="" class="RktModLink" data-pltdoc="x"><span class="RktSym">net/uri-codec</span></a> library follows this convention,
encoding a space as <span class="RktInBG"><span class="hspace"></span><span class="RktIn">+</span><span class="hspace"></span></span> and decoding <span class="RktInBG"><span class="hspace"></span><span class="RktIn">+</span><span class="hspace"></span></span> as a space.
In addition, since there appear to be some broken decoders on the
web, the library also encodes <span class="RktInBG"><span class="hspace"></span><span class="RktIn">!</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">~</span><span class="hspace"></span></span>, <span class="RktInBG"><span class="hspace"></span><span class="RktIn">'</span><span class="hspace"></span></span>,
<span class="RktInBG"><span class="hspace"></span><span class="RktIn">(</span><span class="hspace"></span></span>, and <span class="RktInBG"><span class="hspace"></span><span class="RktIn">)</span><span class="hspace"></span></span> using their hex representation, which is
the same choice as made by the Java’s <span class="stt">URLEncoder</span>.</p><h4 x-source-module="(lib "net/scribblings/net.scrbl")" x-part-tag=""uri-codec-proc"">3.1<tt> </tt><a
