The EUC-JP profile threw on every two-byte character. It now maps the rows
0xA1-0xFE through a 94x94 table taken from Microsoft code page 932 (JIS X 0208
plus NEC row 13 and the NEC-selected IBM rows), and encodes a code point to its
lowest cell. Unassigned cells answer UNASSIGNED_CODE, a bad trail byte
INVALID_ENCODE, and a cut pair SRC_BUFFER_END. Three-byte JIS X 0212 characters
still throw.

sceCesUcsProfileInitEucJpCp51932 returns a profile for EUC-JP, and
sceCesMbcsUcsContextInit now keeps the profile in the context. The
multibyte string conversions (UTF-8, UCS-2, their length queries) and
sceCesEucJpToUcs2 convert ASCII and the JIS X 0201 half-width katakana
for that profile, and every character for the existing CP1252/CP1251
profiles. Two- and three-byte JIS X 0208/0212 characters throw, since
their mapping table is not present.
Metal Gear Solid 4 Master Collection (PPSA18194) imports the set in its
game executable, which fails to load without it.
