| '''Remarks'''
| |
| •
| |
| Only the original equipment manufacturer (OEM) code page installed with Windows XP appears correctly in a command prompt window that uses Raster fonts. Other code pages appear correctly in full-screen mode or command prompt windows that use TrueType fonts.
| |
| •
| |
| You do not need to prepare code pages, as in MS-DOS.
| |
| •
| |
| Programs that you start after you assign a new code page use the new code page, however, programs (except Cmd.exe) that you started before assigning the new code page use the original code page.
