naming problem

[HEGREN]

Hi its my first post here, Im sorry for my poor english.
I found a minor issue in naming screen with japanese character.

It displays hiragana "らりるれる" but its supposed to be "らりるれろ".
In katakana, it shows "ラリルレル" but "ラリルレロ" is correct.

1 byte characters are displayed correctly but after setting a name using 1 byte characters, inputted name disappears
and name field remains blank.

This seems to happen in games that use this type of naming screen like 7th dragon, patapon.
I tried changing fonts but didnt work.
I dont have programming skill atall but is there anything I can do to solve this? Thanks.
