* Besides deciding which hinter to use, you can also decide which
* hinting algorithm to use. See @FT_LOAD_TARGET_XXX for details.
*
* Note that the auto-hinter needs a valid Unicode cmap (either a native
* one or synthesized by FreeType) for producing correct results. If a
* font provides an incorrect mapping (for example, assigning the
* character code U+005A, LATIN CAPITAL LETTER Z, to a glyph depicting a
* mathematical integral sign), the auto-hinter might produce useless
* results.
