sceFontCharactersRefersTextCodes fills a 64-byte FontTextCodes with the
order and code of a text character and keeps the current, start and
term characters at +0x28, +0x30 and +0x38. The traversal follows the
PS4 11.00 libSceFont.sprx disassembly posted in the review of #4050,
which implemented the same rules: Refers never compares the character
with the term and returns null for a clustered or synthetic character,
sceFontTextCodesStepNext returns null at the term after visiting it,
sceFontTextCodesStepBack returns null at the start character, and both
steps skip synthetic characters. Null from StepNext at the end of the
chain and from StepBack at the head of the chain is assumed and not
covered by the report.
The signatures follow Orbital's IDA type database and SharpProspero. A
null cursor or output returns null as in KytyPS5; a null text character
throws. guest_font_tests gets configure_windows_unwind so the expected
exception reaches the test on Windows.

sceFontSetScriptLanguage, sceFontGetScriptLanguage,
sceFontSetTypographicDesign and sceFontGetTypographicDesign threw. With
the signatures SharpProspero declares, a font handle now keeps the
language set for each script and the feature set for each typographic
design, under the handle's lock, and returns them, with 0 for one never
set. They do not change shaping or rendering yet; TechnicalDebt records
the assumptions.

Create, destroy, clear, write runs, step through them and read the
line metrics, following KytyPS5. Layouts from SharpProspero.

sceFontOpenFontSet failed for every set type, so PPSA21564 drew no text
in system fonts (the title screen copyright line, credits, button
guides). It now loads the set's primary font file from
ANYPS5_SYSTEM_FONTS, or anyps5-fonts beside the executable: console
files under their own names first, then openly licensed substitutes
(Noto Sans, Noto Sans Mono, Noto Sans Thai, Noto Sans CJK). The
PS5-only JG2 set types are accepted.
System font handles use the system font context. Their faces are
loaded by FreeType in host memory: about 1 MiB per CJK face does not
fit the font memory the title sizes for the console's fonts, and
sceFontCreateRenderer then failed with ALLOCATION_FAILED. Handles of
the same font file share one copy of its bytes.
