+ * This is the documentation for the library interface of wimlib 1.3.3. If you

* \section encodings Locales and character encodings
*
* To support Windows as well as UNIX, wimlib's API typically takes and returns
- * strings of "tchars", which are in a platform-dependent encoding.
+ * strings of ::wimlib_tchar, which are in a platform-dependent encoding.
*
- * On Windows, each "tchar" is 2 bytes and is the same as a "wchar_t", and the
- * encoding is UTF-16LE.
+ * On Windows, each ::wimlib_tchar is 2 bytes and is the same as a "wchar_t",
+ * and the encoding is UTF-16LE.
*
- * On UNIX, each "tchar" is 1 byte and is simply a "char", and the encoding is
- * the locale-dependent multibyte encoding. I recommend you set your locale to a
- * UTF-8 capable locale to avoid any issues. Also, by default, wimlib on UNIX
- * will assume the locale is UTF-8 capable unless you call wimlib_global_init()
- * after having set your desired locale.

* \section Limitations
*
* without mounting it, other than by adding, removing, or extracting an
* entire image. The FUSE mount feature should be used for this purpose.
* - Currently, Microsoft's @a image.exe can create slightly smaller WIM files
- * than wimlib when using maximum (LZX) compression because it knows how to
- * split up LZX compressed blocks, which is not yet implemented in wimlib.
+ * than wimlib (~2% or 3% smaller) when using maximum (LZX) compression.
* - wimlib is experimental and likely contains bugs; use Microsoft's @a
* imagex.exe if you want to make sure your WIM files are made "correctly".
* - The old WIM format from Vista pre-releases is not supported.
