When I tried C-u C-x = on the € in your email, I got this:
,----
| character: € (8364, #o20254, #x20ac)
| preferred charset: unicode (Unicode (ISO10646))
| code point: 0x20AC
| syntax: _ which means: symbol
| category: c:Chinese h:Korean j:Japanese
| buffer code: #xE2 #x82 #xAC
| file code: #xE2 #x82 #xAC (encoded by coding system raw-text-unix)
| display: by this font (glyph code)
| dejavu sans mono:pixelsize=14:foundry=unknown:weight=medium:slant=r:width=normal (#x66A)
| Unicode data:
| Name: EURO SIGN
| Category: Symbol, Currency
| Combining class: Sc
| Bidi category: Sc
|
| Character code properties: customize what to show
| name: EURO SIGN
| general-category: Sc (Symbol, Currency)
| canonical-combining-class: 0 (Spacing, split, enclosing, reordrant, and Tibetan subjoined)
| bidi-class: ET (European Number Terminator)
| mirrored: N
|
| There are text properties here:
| auto-composed t
| charset windows-1252
`----
which is almost correct. (Category seems wrong to me.)
Note that the glyph code for a ttf is the physical position in the
glyf table in the sfnt file, not a character set code point.
I typically start this this command line (by way of an entry in my
icewm menu):
,----
| emacs --enable-font-backend -xrm '*FontBackend: xft' -xrm 'emacs.font: DejaVu Sans Mono:pixelsize=14'
`----
and then run this function:
,----
| (defun jhc-backend-xft-fonts () "" (interactive)
| (set-fontset-font (frame-parameter nil 'font)
| 'han '("SimHei" . "unicode-bmp"))
| (set-fontset-font (frame-parameter nil 'font)
| 'arabic '("Lucida Sans Typewriter" . "unicode-bmp"))
| (set-fontset-font (frame-parameter nil 'font)
| 'yi '("SIL Yi" . "unicode-bmp"))
| (set-fontset-font (frame-parameter nil 'font)
| 'thai '("Lucida Sans Typewriter" . "unicode-bmp"))
| )
`----
That is not perfect; there are still several holes in font coverage
which need to be filled code-point by code-point rather than script-
by-script as above, but it is getting there.....
