\class Internat
|
|
\brief Internationalisation support.
|
|
|
|
This class is used to help internationalisation and in general
|
|
compatibility with different locales and character sets.
|
|
It deals mostly with converting numbers, but also has important
|
|
functions to convert to/from UTF-8, which is used in XML files
|
|
and on Mac OS X for the filesystem.
