The syntax to add any characters to the charset table looks like:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="charset" mode="assign">
<plus>
<name>charset</name>
<charset>
<int>0x3220</int> <!-- PARENTHESIZED IDEOGRAPH ONE -->
</charset>
</plus>
</edit>
</match>
To remove any characters from the charset table:
<match target="scan">
<test name="family">
<string>Buggy Sans</string>
</test>
<edit name="charset" mode="assign">
<minus>
<name>charset</name>
<charset>
<int>0x06CC</int> <!-- ARABIC LETTER FARSI YEH -->
<int>0x06D2</int> <!-- ARABIC LETTER YEH BARREE -->
<int>0x06D3</int> <!-- ARABIC LETTER YEH BARREE WITH HAMZA ABOVE -->
</charset>
</minus>
</edit>
</match>
You could also use the range element for convenience:
...
<charset>
<int>0x06CC</int> <!-- ARABIC LETTER FARSI YEH -->
<range>
<int>0x06D2</int> <!-- ARABIC LETTER YEH BARREE -->
<int>0x06D3</int> <!-- ARABIC LETTER YEH BARREE WITH HAMZA ABOVE -->
</range>
</charset>
...
The OT spec says:
"When building a Unicode font for Windows, the platform ID should be 3 and the
encoding ID should be 1. When building a symbol font for Windows, the platform
ID should be 3 and the encoding ID should be 0."
We were ignoring the SYMBOL_CS entry before. It's UTF-16/UCS-2 like the
UNICODE_CS.
Also, always use UTF-16BE instead of UCS-2BE. The conversion was doing
UTF-16BE anyway.
Last night in between my dreams I also noticed that we support Unicode
values up to 0x01000000 and not 0x00100000 which I thought before.
This covers the entire Unicode range.
Protect cache against future expansions of FcLangSet (adding new
orth files). Previously, doing so could change the size of
that struct. Indeed, that happened between 2.6.0 and 2.7.3, causing
crashes. Unfortunately, sizeof(FcLangSet) was not checked in fcarch.c.
This changes FcLangSet code to be able to cope with struct size changes.
And change cache format, hence bumping from 2 to 3.
Before a NULL config was passed down adn essentially FcFileScan was
equivalent to FcFreeTypeQuery. Now fc-scan tool correctly applies
the configuration to the scanned patterns.
The East Asian double-byte codepages have characters with backslash as
the second byte, so we must use _mbsrchr() instead of strrchr() when
looking at pathnames in the system codepage.
Must not call FcStrFree() on a value returned by
FcStrBufDoneStatic(). In the Windows code don't bother with dynamic
allocation, just use a local buffer.
