# asciifolding
[![Build Status](https://travis-ci.com/mpaltun/asciifolding.svg?branch=master)](https://travis-ci.com/mpaltun/asciifolding)
Rust port of Lucene's [Ascii folding filter](http://lucene.apache.org/core/8_0_0/analyzers-common/org/apache/lucene/analysis/miscellaneous/ASCIIFoldingFilter.html)

From Lucene documentation:
> This class converts alphabetic, numeric, and symbolic Unicode characters which are not in the first 127 ASCII characters (the "Basic Latin" Unicode block) into their ASCII equivalents, if one exists.
