(1) Aliases not supported by version 3 are colored blue. Refer to the "Supported by versions" column to find if the whole charset including aliases is unsupported by IE3.
(2) "CS" after the version number signals that the support is contained only in the "Complex Script" version of Internet Explorer. The Complex Script versions are labeled as "Hebrew", "Arabic", "Middle East" or "Thai".
(3) BOM stands for Byte Order Mark and are the first 2 bytes of a UCS-2 document.
(4) MLANG.DLL is the charset translation library inside IE. MLANG uses the same code page IDs as Windows but not all MLANG IDs are available on all versions of Windows. In other words you can use the same code page ID to pass into MultiByteToWideChar() but not every code page ID listed here is available for all versions of Windows, even with the appropriate language pack. For example you can not use MultiByteToWideChar() with code page 65001 on Windows 95.
