sceCesRefersUcsProfileCp858 threw. It now returns a single-byte profile
accepted by sceCesSbcToUtf8, sceCesUtf8ToSbc and the MBCS context
conversions. Code page 858 is code page 850 with byte 0xD5 mapped to the
euro sign (U+20AC) instead of U+0131; that is the whole high half of
ICU's ibm-858_P100-1997.ucm. Bytes 0x00-0x7F stay unchanged, as in the
other single-byte profiles.

sceCesRefersUcsProfile threw for every code page except 1250, 1251 and
1252. Twenty-seven more now return a profile that sceCesSbcToUtf8,
sceCesUtf8ToSbc and the MBCS context conversions accept: ISO 8859-1,
-2, -4, -5, -9, -10, -13, -14, -15 and -16, code pages 437, 737, 775,
850, 852, 855, 860, 861, 862, 863, 865 and 866, KOI8-R, KOI8-U and
Windows 1254, 1256 and 1258.
SingleByte.hpp holds the high half of each table, taken from the
public mapping files at unicode.org: ISO8859, Microsoft's PC tables,
VENDORS/MISC for KOI8 and Microsoft's best-fit tables for 1254, 1256
and 1258, the same source and derivation as the existing Cp1250 table,
whose high half equals bestfit1250's byte table. Bytes 0x00-0x7F are
unchanged in all of them, and every table maps its 256 bytes to 256
distinct BMP characters. The three existing profiles keep their
tables; one lookup now serves them all.
Profiles whose public table leaves bytes undefined (ISO 8859-3, -6, -7,
-8, -11, code pages 857, 864, 869), maps bytes to private use (874,
1253, 1255, 1257) or has no public table here still throw.
guest_ces checks that each new profile is a distinct, stable pointer,
four bytes per table against the source, a round trip of every byte
through sceCesSbcToUtf8 and sceCesUtf8ToSbc, UNASSIGNED_CODE for a
character outside the table, and a KOI8-R string through an MBCS
context in both directions.
