That doesn't surprise me; I'd expect you to get the font's .notdef glyph (which might be a blank space, as in this example, or a box, or some other symbol). What you want is a character that has a zero-width, invisible glyph; if the font supports any of the Unicode characters such as ZWNBSP or ZWNJ or WJ or CGJ, etc., that ought to work. Or character 13 (CR) is a likely bet, too.
