<a name="48" href="#48">48</a> <em> * This class has the purpose of supportting of parsing a URI reference to</em>

<a name="50" href="#50">50</a> <em> * be transported and the charset of the document.</em>
<a name="51" href="#51">51</a> <em> * <p></em>
<a name="52" href="#52">52</a> <em> * A URI is always in an "escaped" form, since escaping or unescaping a</em>
<a name="53" href="#53">53</a> <em> * completed URI might change its semantics. </em>
<a name="54" href="#54">54</a> <em> * <p></em>
<a name="55" href="#55">55</a> <em> * Implementers should be careful not to escape or unescape the same string</em>
<a name="56" href="#56">56</a> <em> * more than once, since unescaping an already unescaped string might lead to</em>
<a name="57" href="#57">57</a> <em> * misinterpreting a percent data character as another escaped character,</em>
<a name="58" href="#58">58</a> <em> * or vice versa in the case of escaping an already escaped string.</em>
<a name="59" href="#59">59</a> <em> * <p></em>
<a name="60" href="#60">60</a> <em> * In order to avoid these problems, data types used as follows:</em>
<a name="61" href="#61">61</a> <em> * <p><blockquote><pre></em>
<a name="62" href="#62">62</a> <em> * URI character sequence: char</em>
<a name="63" href="#63">63</a> <em> * octet sequence: byte</em>

<a name="66" href="#66">66</a> <em> *</em>
<a name="67" href="#67">67</a> <em> * So, a URI is a sequence of characters as an array of a char type, which</em>
<a name="68" href="#68">68</a> <em> * is not always represented as a sequence of octets as an array of byte.</em>
