This 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.
Original KchmViewer is written by Georgy Yunaev.

Features:
    Standalone viewer, depends on Qt 5 or Qt 6 only. Does not require
KDE, GNOME or wxWidgets toolkit. Completely safe and harmless.
JavaScript can be disabled in the settings, optionally warns you before
opening an external web page, or switching to another help file.
Correctly detects and shows encoding of any valid chm file. Correctly
shows non-English chm files, including Cyrillic, Chinese, Japanese and
others. Correctly searches in non-English chm files using chm built-in
search index. Shows an appropriate image for every TOC entry. Has
complete chm index support, including multiple index entries,
cross-links and parent/child entries in index. Persistent bookmarks
support. Allows to store bookmarks even if "Favorites" window was not
enabled for this chm file. Also stores the screen position for every
bookmark. You can also edit/delete bookmarks. For any opened chm file,
stores the last opened window, search history, bookmark history, font
size and so on, so when you open this file again, everything is always
on the place. Has easy and powerful search-in-page support. Allows to
increase or decrease the font size, so physically handicapped people
can read texts easily. Has standard Back/Forward/Home navigation. Can
print the opened pages on a standard printer (usually via CUPS). Has
complex search query support. You can use search queries like "lazy
people" +learn -not.
