<p>
This module allows developers to easily construct powerful
<span class="type">DeeTermFilter</span>s with ease. The filters leverage the ICU
framework to provide world class transliteration features.
</p>

The filters can be employed manually by calling <a class="link" href="dee-1.0-Dee-ICU-Extensions.html#dee-icu-term-filter-apply" title="dee_icu_term_filter_apply ()"><code class="function">dee_icu_term_filter_apply()</code></a>

passing the term filter instance as the user data and
