There's one slight problem with your claim - NONE of the characters
listed have codes below 128. Check it out if you don't believe me!

Note that ASCII only defines codes 0 through 127, and there has NEVER
been a standard definition for codes 128 through 255, even on the IBM
PC itself. Check for yourself and you will find at least the following
different sets of definitions for that range:
1. IBM Character Set #1
2. IBM Character Set #2 (aka "PC Character Set").
3. Epson FX-80 Character Set.
4. MS-DOS Codepage 437 (aka "US codepage").
5. MS-DOS Codepage 850 (aka "International codepage").
All of the above are identical for codes 0 through 127, but differ
wildly from each other for codes 128 to 255, and ALL of the above
could be used with MS-DOS 2.11 onwards.
You can also list the recent additions of the Win9x character set
(different from ALL of the above), and of Unicode as well.
