  Applying changes to eucjpms, similar to ujis.
  Note: eucjpms appeared in 5.0 so the original patch,

# Bugs#15375: Unassigned multibyte codes are broken
# into parts when converting to Unicode.
# This query should return 0x003F0041. I.e. it should
# scan unassigned double-byte character 0xA5FE, convert
# it as QUESTION MARK 0x003F and then scan the next
# character, which is a single byte character 0x41.

# convert it as QUESTION MARK 0x003F and then scan
# the next character, which is a single byte character 0x41.
