Bug #68107 mysql client with --default-character-set=ujis crashes

Description:
mysql command-line client crashes when it writes to .my_history.

I have realized this issue appears with --default-character-set= ujis or sjis or  cp932, in Version 5.6.9 rpm(x86_64) and compiled from source-code.
It doesn't appear in 5.5.29's client.

How to repeat:
$ mysql --default-character-set=ujis

Noted in 5.6.12, 5.7.2 changelogs.

The mysql client incorrectly used latin1 for certain comparisons even
if started with a multibyte default character set, resulting in a 
client crash.
