uChmViewer is a fork of the KchmViewer with some improvements. uChmViewer is a
chm (MS HTML help file format) and epub viewer, written in C++ using Qt
framework.

The main advantage of uChmViewer is extended support for non-English
languages. Unlike others, uChmViewer in most cases correctly detects chm file
encoding, correctly shows tables of context of Russian, Korean, Chinese and
Japanese help files. It also correctly searches text in non-English help
files, including Korean, Chinese and Japanese.
