The code pages for Greek and Russian are supported on MS-DOS, Microsoft Windows, and Macintosh platforms. Visual FoxPro also supports double-byte character sets for languages such as Japanese, Korean, Traditional Chinese, and Simplified Chinese; however, Unicode is not supported . Visual FoxPro supports collation sequences for languages such as Japanese, German, Traditional Chinese, and Icelandic.

Например:

STRCONV(cExpression, nConversionSetting [, nLocaleID])
Converts character expressions between single-byte, double-byte, UNICODE, and locale-specific representations
