 - [EUC-JIS-2004 and Shift_JIS-2004 profiles](../../../core/libs/prx/libSceCesCs/JisX0213.hpp) (libSceCesCs) - the errors follow the other JIS profiles, unmeasured; the tables were measured on a PS5 (`sceCesMbcToUtf32` over every one-, two- and `0x8F`-led three-byte sequence, `sceCesUtf32ToMbc` over U+0000-U+110001). Both planes follow Project X0213's JIS X 0213:2004 table with the 90 cells it notes as having a fullwidth form mapped to that form, and also cells 1-17, 1-79 and 2-15 to 2-18 (U+FFE3, U+FFE5, U+FF07, U+FF02, U+FF0D, U+FF5E); U+203E and U+00A5 still encode into 1-17 and 1-79. EUC-JIS-2004's SS3 reads JIS X 0212 in the rows plane 2 leaves empty, both ways, with plane 2 preferred for a code point in both. The 25 cells the standard maps to two code points are unassigned both ways on the console (`A4F7` gives `0x805C0020`; U+304B U+309A encodes U+304B, then fails). Bytes below `0x80` are ASCII. The `sceCesEucJp*` and `sceCesSJis*` scalar helpers keep refusing these two profiles.
 - [Single-byte profiles](../../../core/libs/prx/libSceCesCs/SingleByte.hpp) (libSceCesCs) - the console's tables for these 27 profiles are not verified. Each returns a profile accepted by `sceCesSbcToUtf8`, `sceCesUtf8ToSbc` and the MBCS context conversions, with bytes 0x00-0x7F unchanged and the high half of a public table: ISO 8859-1, -2, -4, -5, -9, -10, -13, -14, -15 and -16 from [unicode.org](https://unicode.org/Public/MAPPINGS/ISO8859/), code pages 437, 737, 775, 850, 852, 855, 860-863, 865 and 866 from [Microsoft's PC tables](https://unicode.org/Public/MAPPINGS/VENDORS/MICSFT/PC/), KOI8-R and KOI8-U from [unicode.org](https://unicode.org/Public/MAPPINGS/VENDORS/MISC/), and 1254, 1256 and 1258 from Microsoft's [best-fit tables](https://unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WindowsBestFit/), whose unassigned bytes map to C1 controls as in Cp1250. Profiles whose public table leaves bytes undefined or maps them to private use still throw
 - [sceCesRefersUcsProfileCp858](../../../core/libs/prx/libSceCesCs/SingleByte.hpp) (libSceCesCs) - the console's table is not verified. The profile is the Cp850 one with byte 0xD5 mapped to U+20AC instead of U+0131, which is the whole high half of ICU's [ibm-858_P100-1997.ucm](https://github.com/unicode-org/icu-data/blob/main/charset/data/ucm/ibm-858_P100-1997.ucm); bytes 0x00-0x7F stay unchanged as in the other single-byte profiles, not swapped as in IBM's control mapping

 - [EUC-KR, UHC and Big5 conversions](../../../core/libs/prx/libSceCesCs/Export.cpp) (libSceCesCs) - the errors are assumed; the decode tables and the Big5 duplicate choices were measured on a PS5 (`sceCesMbcToUtf32` and each `ToUtf8` over every one- and two-byte sequence): UHC and Big5 match, EUC-KR apart from its single bytes. The tables are Microsoft's [CP949.TXT](https://unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP949.TXT), plus `0xA2E8` U+327E from KS X 1001:2002, and [CP950.TXT](https://unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP950.TXT); EUC-KR is CP949 limited to bytes `0xA1`-`0xFE`, below `0x80` ASCII; the KS X 1003 profile is not implemented. User-defined areas answer `UNASSIGNED_CODE`. Big5 encoding takes the lower of two cells except for U+5341 and U+5345, as a PS5's `sceCesUtf32ToMbc` does for every scalar (CP950 takes the higher cell of U+2550, U+255E, U+2561 and U+256A; the console does not). The profiles tag the caller's sheet like the EUC-JP profile
+- [ISO 646 variants and JIS X 0201 profiles](../../../core/libs/prx/libSceCesCs/SingleByte.hpp) (libSceCesCs) - the tables and errors were measured on a PS5 with `sceCesSbcToUtf32` over every byte and `sceCesUtf32ToSbc` over every BMP scalar; the other single-byte forms share them and were not measured separately. The 7-bit sets (ASCII, BS 4730, GB 1988-80, JIS X 0201 Roman and Katakana, KS X 1003 and their `Tilde0x7e` variants) answer `INVALID_ENCODE` for bytes `0x80`-`0xFF`. BS 4730 changes only `0x23` (£), GB 1988-80 `0x24` (¥), JIS X 0201 Roman `0x5C` (¥) and KS X 1003 `0x5C` (₩); the base GB, JIS and KS profiles also map `0x7E` to overline and the `Tilde0x7e` variants keep a tilde. The katakana-only profile maps `0x21`-`0x5F` to U+FF61-U+FF9F and leaves `0x60`-`0x7E` unassigned; the 8-bit katakana profiles use `0xA1`-`0xDF`.
