A string created from a text source in the default horizontal form (0x10)
reported 0x10. TEKKEN: DARK RESURRECTION (PPSA31371) passes the reported form
to sceFontCreateWritingLine, which only accepts 0x11 and 0x12, so the call
failed and the layout width was 0.
On firmware 13.42 sceFontCreateString decides the direction for a default-form
source and sceFontStringGetWritingForm returns the stored form. The string
gets 0x12 when its first strong character is left to right, 0x11 when it is
right to left, and 0x12 when it has none. Left-to-right and right-to-left marks
count as strong, embeddings and overrides do not, and text between an isolate
initiator and its PDI is skipped. Explicit 0x11 and 0x12 sources keep their
form.
The test follows the table reported on the pull request. Which characters are
strong is decided by Unicode block ranges here, not by the full bidi class
tables.
A valid font-set handle with a null output now returns
SCE_FONT_ERROR_INVALID_PARAMETER instead of throwing, matching the
handle, then output, order of the firmware.

ComputeFontGlyphsOutlineProfile read font->library before checking the
handle and cleared the output only after the context lookup, relying on
sceFontGetFontGlyphsOutlineProfile to have validated the handle. It now
rejects a null or non-font handle with SCE_FONT_ERROR_INVALID_FONT_HANDLE
first, clearing a non-null output, then checks the output, then clears it
before the library and context lookups, matching the firmware 13.60 order.
The test also covers a null output with a bad handle and a handle with no
library.

sceFontGetFontGlyphsOutlineProfile reports the maxp maximum contours,
points, composite contours and composite points through the driver slot
at SysDriver+0x70, as libSceFont and libSceFontFt do in firmware 13.60.
A maxp older than 1.0 returns SCE_FONT_ERROR_NO_SUPPORT_FUNCTION, and a
failed call clears the output. Font-set records, which the console
merges over system font entries, still throw.

sceFontGetFontStyleInformation fills the 24-byte style block through the
driver slot at SysDriver+0x48, as libSceFont and libSceFontFt do in
firmware 13.60: the FreeType family and style names, the italic and bold
flags, the OS/2 weight class when it is a multiple of 100 from 100 to 900,
the width class below 10, and 1 plus a right-to-left head direction plus
0x80 for vertical metrics. A font-set record supplies the same fields
directly. A failed call points both names at an empty string and clears
the rest.

sceFontGetFontMetrics fills the 64-byte metrics block through a new
driver slot at SysDriver+0x98, as libSceFont and libSceFontFt do in
firmware 13.60. Form 1 reads hhea, 2 the OS/2 typographic values, 3 the
OS/2 Windows values and 4 the vertical values from vhea or OS/2; 2 and 3
fall back to hhea when OS/2 is missing or gives an empty range. The
bounding box, em size, raw weight deltas and slant follow. A failed call
clears the block and sets both weights to 1.

Without system font files, sceFontOpenFontSet returns
SCE_FONT_ERROR_FONT_OPEN_FAILED and logs `file=(none)` for each call.
Some titles then fail far from the cause: Astro's Playroom (PPSA01325)
lays out text with the failed set and stops on an out-of-heap or invalid
texture assertion (#7714). The first such open now prints the font set
and the directory searched to stderr, with how to supply the fonts.
