Under Windows, the COBOL runtime uses OEM or ANSI character encoding. Therefore, the Windows implementation of XML Extensions
also supports OEM or ANSI character encoding for local character encoding. The
MF_XMLEXT_LOCAL_ENCODING environment variable is ignored by the Windows implementation of XML Extensions.
Note: Microsoft originally introduced OEM character encoding for MS-DOS. While there are multiple OEM code pages in use, the Windows
operating system provides interfaces that allow conversion between the OEM code page in use and Unicode. XML Extensions does
not need to differentiate between code pages. The ANSI code page can be selected as the native character set, in which case,
XML Extensions uses the ANSI code page in use for the conversion to/from Unicode when using the local character encoding.
