bug#23698: 24.5; broken character name

[ynyaaa]

Just after starting emacs -Q, this form returns correct value.

(get-char-code-property #xE01 'name)
=>"THAI CHARACTER KO KAI"

Then display THAI characters by typing this.
  M-x list-charset-chars RET thai-iso8859-11 RET

After THAI characters are displayed, the form returns wrong value.

(get-char-code-property #xE01 'name)
=>"LETTER KO KAI"

For other THAI characters, get-char-code-property returns wrong names.
