| The library has the full repertoire of single character generators for |
| character classification. This includes the usual <code class="computeroutput"><span class="identifier">alnum</span></code>, |
| <code class="computeroutput"><span class="identifier">alpha</span></code>, <code class="computeroutput"><span class="identifier">digit</span></code>, <code class="computeroutput"><span class="identifier">xdigit</span></code>, |
| etc. generators. These generators have an associated <a class="link" href="../karma_basics.html#spirit.karma.reference.karma_basics.character_encoding_namespace">Character |
| Encoding Namespace</a>. This is needed when doing basic operations |
| such as forcing lower or upper case. |
