Problem with the input of '€' (U+20AC EURO SIGN) with ~/.Xmodmap

[Mike FABIAN]

My ~/.Xmodmap contains:

    keysym e = e NoSymbol EuroSign   NoSymbol
    keysym c = c NoSymbol 0x010000a2 currency

Using that, I can input '€' (U+020AC EURO SIGN),
'¢' (U+00A2 CENT SIGN), and '¤' (U+00A4 CURRENCY SIGN) by typing
the following key sequences:

    AltGr e 　　　　→   €
    AltGr c         →   ¢
    Shift+AltGr c   →   ¤

That works fine in all applications *except* XEmacs.

When I use that key sequence to type an € in XEmacs, the cursor
advances but I don't see a glyph.  When positioning the cursor on that
character and checking with 'C-u C-x =' I get:

   €Char: € (U+20AC greek-iso8859-7 36) point=1032 of 1128(91%) column 0 

i.e. the € has been input correctly, the problem is only that it is
represented in the Greek character set, therefore a Greek font is used
and that doesn't have the € character (X11 core fonts are used, not
Xft).

If I input the € by other means, for example

    - pasting from another application
    - using the input methods t-latn-pre or t-rfc1345 from scim-m17n

I get 

    Char: € (U+20AC latin-iso8859-15 36) point=1200 of 1660(72%) column 9 

and the € is visible.

Why is the Greek charset used when € is input via ~/.Xmodmap?

When trying to input ¢ via ~/.Xmodmap, it is even worse, I only get
the regular ASCII 'c' than.

But ¢ can be input just fine by pasting from another application and
by using an input method like scim-m17n.

So why doesn't this work with ~/.Xmodmap?
