Hello workers,

I have noticed, that DOS converts some non-ASCII
characters to ASCII characters in filenames. I
have codepage 437 as my standard codepage, and in
that case the following characters are converted:

            90 e        A0 a
81 u        91 Æ (AE)   A1 i
82 e                    A2 o
83 a        93 o        A3 u
84 a        94 o        A4 Ñ (~N)
85 a        95 o
86 Å (oA)   96 u
87 Ç (,C)   97 u
88 e
89 e        99 o
8A e        9A u
8B i
8C i
8D i
8E a

The hex codes are given together with the
characters they are converted to. Most characters
just loose their accents.

Is this documented behaviour? Can it be turned
off? I think it has something to do with DOS
converting every filename to capitals.

Should we check for these things in (for
instance) djtarx, unzip, tar, Emacs, etc.?
I encountered this when unzipping files
containing 128+ characters, actually.

JFYI.

Groente, Michel.
