It's there, it's just not obviously there.

The closest thing is the Microsoft CP874 mapping, which is almost
identical to TIS620-2533. The difference lies in extra codepoints in
C1 added by Microsoft in CP874, including 0x80 (Euro), 0x85
(horizontal ellipsis), and 0xA0 (non-breaking space).

This table is correct, and will work for pure TIS620-2533 and CP874.

Note that this is a mapping for the ASCII-version of TIS620-2533, not
the EBCDIC version. IBM and Apple also have their own variants.
