4215 * tdata. For each one that doesn't, we must WCToMB it

4218 * It would probably be more robust to just bite the bullet
4219 * and WCToMB each individual Unicode character one by one,
4220 * then MBToWC each one back to see if it was an accurate
4221 * translation; but that strikes me as a horrifying number
4222 * of Windows API calls so I want to see if this faster way
4223 * will work. If it screws up badly we can always revert to
