mojibake against an input character.

HeTeMuLu Creator is a tag insertion type HTML editor written by Kenji Hosimoto.
In the text area, I can input Japanese kanji characters through XIM, e.g.
Fcitx.
However, when I input a certain kanji character, it isn't shown properly.

How to reproduce:
 1. Extract hcre110a.zip.
 2. Run Hetecre.exe in Japanese locale (i.e. LANG=ja_JP.UTF-8).
 3. Click Close in "A Tip for Today" window.
 4. Input "縋る" (Sugaru) with Japanese IME.

Expected result:
 It shows "縋る" in the text area.

Actual result:
 It shows "・vる" in the text area (see the attachment).

Note:
 * When I open a text file which contains "縋", it shows without issues.
   I can paste the character, too. Therefore, it's an input side bug, I think.
 * I can also reproduce with JIS X 0208 level 2 characters whose leading byte
value greater than or equals to 0xE0.
