/*
* WTF is this shit - a short story by CrazyEddie
*
* One of the following implementations are for use when CEGUI::String is
* not the unicode capable versions. Neither of these implementations
* perform ideally, which is why I left both here - as it is intended
* that eventually we may come back here and improve this.
*
* The codecvt version (1st one) overall does a better job, because when
* the locale is mbcs compliant, it is able to produce encoded output
* that will likely match what client code is using elsewhere. The
* problem with it is that when using a non-mbcs locale (such as the
* basic C or maybe an ISO8859-1 locale, a source character that will
* not fit causes the conversion to fail (and we throw an exception).
*
* The ctype version (2nd one) provides us the facility to use a 'default'
* character for those codes that can not be represented by a single
* character in the target locale - and the conversion will always
* succeed, though some data may be lost in translation. The 'bad'
* part about using ctype for conversion is that it is a single code
* unit mapping, which means when the user has a mbcs locale, characters
* that should be correcly represented (i.e they would be converted by
* the codecvt version) are instead replaced by the default character.
*
* The ideal scenario for us would be able to use the codecvt approach but
* also have a default character for use when conversion is impossible. This
* would be the closest match to what is done on the Win32 implementation
* that uses WideCharToMultiByte passing the CP_ACP value.
