-// Conversion routines between different character encodings, to be used in
-// Push/Get/Match handlers of SqPlus. It enables using both of char* and
-// wchar_t* as function arguments.
-//
-// When converting from wchar_t to char, the choice is between using a Latin1
-// or a UTF8 representation in 8-bit mode. This is probably most useful if
-// Squirrel is compiled in ANSI mode and the app uses some wchar_t strings
-// (UNICODE mode on Win32).
-//
-
-// A char is either
-// - A Latin1 character (first code page, coincides with Unicode points 0..255)
-// - Part of an UTF8 character
-//
-// Note: SQUTF8 requires Squirrel sources that have been patched for UTF8 strings
-// internally (when converting function arguments).
