You'll get weird drawing results with invalid characters in the
field, but I don't think it will cause a crash. You want to avoid
calling FldInsert with characters that have code points less than
0x20, other than tab or linefeed.
The set of characters that can safely be passed to FldHandleEvent are:
chrTab, chrBackspace, chrLineFeed, chrLeftArrow, chrRightArrow,
chrDownArrow, chrUpArrow, and TxtCharIsPrint(theCharacter) == true.
