read Chinese character from a textbox

Hello, I have a textbox displaying a chinese character. I want to read the character into a string. But it's always rendered as "?"

This happens whether I use .text or .value

Getting the URL Escape code for the character would be fine
For example, 用 could be returned as %E7%94%A8

http://graphemica.com/%E7%94%A8

works just the same

MS Access 2003, by the way, if it makes a difference.
