I was using an customized font with old verison of Flutter (Mar 6),
and Thai can be displayed with TextStyle(fontWeight: FontWeight.w700, fontSize: size, color: color);

But after I upgrade to latest version of Flutter , Thai text can not be displayed , other languages are ok.
String text = 'abc123บันทึก'; only 'abc123' could be displayed.

If I change w700 to w600, it works.

Could you help to fix it ?
