* COPYRIGHT: See COPYING in the top level directory
* PROJECT: ReactOS kernel
* FILE: ntoskrnl/rtl/nls.c
- * PURPOSE: National Language Support (NLS) functions
- * UPDATE HISTORY:
- * 20/08/99 Created by Emanuele Aliberti
- * 10/11/99 Added translation functions.
+ * PURPOSE: Bitmap functions
*
- * NOTE:
- * Multi-byte code pages are not supported yet. Even single-byte code
- * pages are not supported properly. Only stupid CHAR->WCHAR and
- * WCHAR->CHAR (Attention: data loss!!!) translation is done.
- *
- * TODO:
- * 1) Implement code to initialize the translation tables.
- * 2) Use fixed translation table for translation.
- * 3) Add loading of translation tables (NLS files).
- * 4) Add multi-byte translation code.
+ * PROGRAMMERS: Eric Kohl
