Japanese keyboard for alphabet input

[TSK_Panda]

Hi,

Most of our clients are Japanese, and when they use a Japanese keyboard to input Roman characters, they have two options: half-width and full-width.

We want to enforce a restriction that requires all alphanumeric characters and spaces in company names to be entered in half-width, rejecting full-width alphanumeric characters.

I would appreciate any insight on this matter.
