Okay, I will install it if nobody objects.

I don't know if it's used on DOS; the author of the LaTeX file
mentioned OS/2.
If I understand it correctly, `cp850-decode-table' in `codepage.el' is
derived from Latin-1 (iso-8859-1). As Latin-1 doesn't include the EUR
sign, cp858 can't be derived from Latin-1. But `codepage.el' doesn't
seem to support Latin-9 (iso-8859-15) which includes the EUR (and some
other changes to Latin-1). I didn't find anything related to Latin-9
there. I'm not sure if `codepage.el' provides any codepages that
include the EUR sign:
;; Support for the Windows 12xx series of codepages that MS has
;; butchered from the ISO-8859 specs. This does not add support for
;; the extended characters that MS has added in the 128 - 159 coding
;; range, only translates those characters that can be expressed in
;; the corresponding iso-8859 charset.
If it's not possible to provide full support of cp858 (including the
EUR) within `codepage.el', we should probably treat it as cp850 (in
the same way as windows-1252 is treated as Latin-1, if I understand
correctly).
Eli?
Bye, Reiner.
