@kkitahara/unicode-tools v1.0.8

UnicodeTools

ECMAScript modules which implement some of the Unicode® Standard.

Currently, only the default/canonical case folding (the Unicode® Standard 12.0.0, section 3.13, R4/D145) is implemented.

New functionalities may be added on (author's) demand in future.

Installation

npm install @kkitahara/unicode-tools
