<p class="module-desc"><p>This module is based on Python's <a class="reference external" href="https://pypi.org/project/Unidecode/">Unidecode</a> module by Tomaz Solc, which in turn is based on the <a class="reference external" href="https://metacpan.org/pod/Text::Unidecode">Text::Unidecode</a> Perl module by Sean M. Burke.</p>
<p>It provides a <a class="reference external" href="#unidecode,string">unidecode proc</a> that does Unicode to ASCII transliterations: It finds the sequence of ASCII characters that is the closest approximation to the Unicode string.</p>
<p>For example, the closest to string &quot;Äußerst&quot; in ASCII is &quot;Ausserst&quot;. Some information is lost in this transformation, of course, since several Unicode strings can be transformed to the same ASCII representation. So this is a strictly one-way transformation. However, a human reader will probably still be able to guess from the context, what the original string was.</p>
<p>This module needs the data file <tt class="docutils literal"><span class="pre"><span class="Identifier">unidecode</span><span class="Operator">.</span><span class="Identifier">dat</span></span></tt> to work: This file is embedded as a resource into your application by default. You can also define the symbol <tt class="docutils literal"><span class="pre"><span class="Operator">--</span><span class="Identifier">define</span><span class="Punctuation">:</span><span class="Identifier">noUnidecodeTable</span></span></tt> during compile time and use the <a class="reference external" href="#loadUnidecodeTable">loadUnidecodeTable proc</a> to initialize this module.</p>

Loads the datafile that <a class="reference external" href="#unidecode,string">unidecode</a> needs to work. This is only required if the module was compiled with the <tt class="docutils literal"><span class="pre"><span class="Operator">--</span><span class="Identifier">define</span><span class="Punctuation">:</span><span class="Identifier">noUnidecodeTable</span></span></tt> switch. This needs to be called by the main thread before any thread can make a call to <tt class="docutils literal"><span class="pre"><span class="Identifier">unidecode</span></span></tt>.
