+/*! \class TQTsciiCodec qtsciicodec.h
+ \reentrant
+ \ingroup i18n
+
+ \brief The TQTsciiCodec class provides conversion to and from the Tamil TSCII encoding.
+
+ TSCII, formally the Tamil Standard Code Information Interchange
+ specification, is a commonly used charset for Tamils. The
+ official page for the standard is at
+ \link http://www.tamil.net/tscii/ http://www.tamil.net/tscii/\endlink
+
+ This codec uses the mapping table found at
+ \link http://www.geocities.com/Athens/5180/tsciiset.html
+ http://www.geocities.com/Athens/5180/tsciiset.html\endlink.
+ Tamil uses composed Unicode which might cause some
+ problems if you are using Unicode fonts instead of TSCII fonts.
+
+ Most of the code here was written by Hans Petter Bieker
+ and is included in TQt with the author's permission and the
+ grateful thanks of the Trolltech team.
