I'm attaching a series of patches for improvements to the Hangul shaper. These provide support for Old Hangul sequences that do not have a precomposed Unicode form, and handle the tone-mark reordering.<br>
<br>
With these patches, we exactly match uniscribe on the wikipedia test corpus using malgun.ttf, except for (a) cases where there's a character that's not supported in the font, so uniscribe gives .notdef but harfbuzz finds a compatibility fallback, and (b) a handful of words where there's an <LV, T> sequence that uniscribe doesn't support (it has no corresponding LVT syllable), but we handle by decomposing to <L, V, T> and applying jamo features.<span class="HOEnZb"><font color="#888888"><br>
