OS/2 Version 2.0 has national language support for twenty-two languages:
OS/2 Version 2.0 provides support for all countries supported by OS/2 Version 1.3, with additional single-byte and double-byte national languages supported. Where a number of the newly supported countries use more than one common language, these languages are supported by OS/2 Version 2.0 as part of the national language support for that country.
OS/2 Version 2.0 provides support for message files which use multiple codepages. This allows an application to select messages from the file using the current codepage for the application's parent process, thereby enabling more comprehensive national language support by applications.
OS/2 Version 2.0 also provides support for bidirectional languages such as Arabic and Hebrew, in conjunction with the national language codepages for these languages, and keyboard and printer monitors implemented by the operating system. In addition, OS/2 Version 2.0 provides enabling support for those countries using bidirectional alphabets such as Arabic and Hebrew.
