Windows Boot Manager displays all characters with the same width in Windows Vista

Windows Boot Manager (Bootmgr.exe) displays all characters with the same width in Windows Vista.

For example, when the string includes multi-byte characters, all single-byte characters are displayed with the multi-byte width. Windows Boot Manager allows for 80 single-byte characters to be shown per line. But the text may be clipped when the characters are displayed as multi-byte characters.

When English characters are displayed with multi-byte width, there is no loss in the functionality. However, lines that have more than 40 characters are truncated. This limitation affects Windows Boot Manager applications.
