A while back we removed Apple Roman encoding support. This broke
symbol fonts (Wingdings, etc) because those fonts come with two
cmaps:
1) platform=1,encoding=0, aka Apple Roman, which maps identity,
2) platform=3,encoding=0, aka MS Symbol font
Now, the reason the Apple Roman removal "broke" these fonts is
obvious, and for the better: these fonts were mapping ASCII and
other Latin chars to symbols.
The reason the fonts didn't work anymore, however, is that we were
mishandling the MS symbol-font cmaps. In their modern incarnation
they are like regular non-symbol-font cmap that map PUA codepoints
to symbols. We want to expose those as such. Hence, this change
just removes the special-handling for that.
Now, the reason this confusion happened, if I was to guess, is either
that FreeType docs are wrong saying that FT_ENCODING_MS_SYMBOL is
the "Microsoft Symbol encoding, used to encode mathematical symbols":
http://www.kostis.net/charsets/symbol.htm
or maybe it started that way, but turned into also mapping MS symbol-
font cmaps, which is a completely different thing. At any rate, I
don't know if there are any fonts that use this thing these days, but
the code here didn't seem to produce charset for any font. By now I'm
convinced that this change is the Right Thing to do. The MS Symbol
thing was called AdobeSymbol in our code by the way.
This fixes the much-reported bug that windings, etc are not usable
with recent fontconfig:
https://bugs.freedesktop.org/show_bug.cgi?id=58641
Now I see PUA mappings reported for Wingdings.
This also fixes:
Bug 48947 - Drop the non-Unicode cmap support gradually
https://bugs.freedesktop.org/show_bug.cgi?id=48947
since the AdobeSymbol was the last non-Unicode cmap we were
trying to parse (very incorrectly).
Lots of code around this change can be simplified. I'll push those
out (including removing the table itself) in subsequent changes.
Passing -Werror in the scandir() checks caused Studio cc to report
"Unrecognized option errors", confusing configure into thinking that
scandir() was not available. Use Studio equivalent flags instead.
Leaves -Werror as the default for all other compilers, including
unknown ones, to flag to them that they need to update their flags
as well if -Werror is not correct for them.

The SGML for these functions exists, and they are named as manpages,
but because they are not mentioned in fontconfig-devel.sgml, no
documentation is ever generated, and installation under --enable-docs
fails.
(The documentation I have written in fontconfig-devel.sgml is boilerplate
so I can get the manpages generated. It's probably wrong.)
All color fonts are designed to be scaled, even if they only have
bitmap strikes. Client is responsible to scale the bitmaps. This
is in constrast to non-color strikes...
Clients can still use FC_OUTLINE to distinguish bitmap vs outline
fonts. Previously FC_OUTLINE and FC_SCALABLE always had the same
value. Now FC_SCALABLE is set to (FC_OUTLINE || FC_COLOR).

This reverts commit a5a384c5ff.
I don't remember what I had in mind for "We will use this property later.", but
the change was wrong. If a font pattern doesn't have any value for element,
it must be interpretted as "it matches any value perfectly. And "perfectly"
must have a score of 0 for that to happen.
This was actually affecting bitmap fonts (in a bad way), as the change made
an outline font to always be preferred over a (otherwise equal) bitmap font,
even for the exact size of the bitmap font. That probably was never noticed
by anyone, but with the font range support this has become clear (and worked
around by Akira). To clean that up, I'm reverting this so I can land the
rest of patches for bug 80873.
https://bugs.freedesktop.org/show_bug.cgi?id=80873#c10
Previously, if the patten didn't request, eg, style, then the style
and stylelang were fully copied from the font, even though the pattern
had a stylelang. Eg:
$ fc-match 'Apple Color Emoji:stylelang=en'
Apple Color Emoji.ttf: "Apple Color Emoji" "標準體"
This change both fixes that and makes the code much more readable. Now:
$ fc-match 'Apple Color Emoji:stylelang=en'
Apple Color Emoji.ttf: "Apple Color Emoji" "Regular"
iconv support was turned off by default in f30a5d76.
Some fonts, like Apple Color Emoji, only have their English
name in a MacRoman entry. As such, decode MacRoman ourselves.
