Codepage 866 Encoding and Decoding

Code Page 866 (CP866), also known as IBM 00866, OEM 866, and MS-DOS Greek, is a character set used primarily for Cyrillic script, specifically for Russian and other languages that use the Cyrillic alphabet, in MS-DOS systems.

Code Page 737 (CP737) consists of 256 characters, where the first 128 characters are the same as ASCII. The remaining 128 characters (0x80 to 0xFF) include box-drawing characters, Cyrillic alphabets and other symbols.
