8c0d1916 | 2018-01-05 12:46:12 | Improve CGJ skipping logic Previously we made CGJ unskippable. Now, if CGJ did NOT prevent any reordering, allow skipping over it. To make this work we had to make changes to the Arabic mark reordering algorithm implementation to renumber moved MCM marks. See comments. Fixes https://github.com/harfbuzz/harfbuzz/issues/554 | |

|
7f9e7f86 | 2017-10-04 13:20:33 | Adjust normalizer for out-of-order marks We are going to implement Unicode Arabic Mark Ordering Algorithm: http://www.unicode.org/reports/tr53/tr53-1.pdf which will reorder marks out of their sorted ccc order. Adjust normalizer to stop combining as soon as dangerous ordering is detected. | |

8b5bc141 | 2016-02-24 19:05:23 | Add get_nominal_glyph() and get_variation_glyph() instead of get_glyph() New API: - hb_font_get_nominal_glyph_func_t - hb_font_get_variation_glyph_func_t - hb_font_funcs_set_nominal_glyph_func() - hb_font_funcs_set_variation_glyph_func() - hb_font_get_nominal_glyph() - hb_font_get_variation_glyph() Deprecated API: - hb_font_get_glyph_func_t - hb_font_funcs_set_glyph_func() Clients that implement their own font-funcs are encouraged to replace their get_glyph() implementation with a get_nominal_glyph() and get_variation_glyph() pair. The variation version can assume that variation_selector argument is not zero. | |

49ef6309 | 2015-11-04 17:27:07 | Adjust the width of various spaces if font does not cover them See discussion here: https://github.com/behdad/harfbuzz/commit/81ef4f407d9c7bd98cf62cef951dc538b13442eb There's no way to disable this fallback, but I don't think it would be needed. Let's hope for the best! Fixes https://github.com/behdad/harfbuzz/issues/153 | |
|
7793aad9 | 2015-11-04 14:48:46 | Normalize various spaces to space if font doesn't support This resurrects the space fallback feature, after I disabled the compatibility decomposition. Now I can release HarfBuzz again without breaking Pango! It also remembers which space character it was, such that later on we can approximate the width of this particular space character. That part is not implemented yet. We normalize all GC=Zs chars except for U+1680 OGHA SPACE MARK, which is better left alone. | |

5209c505 | 2014-07-17 12:23:44 | Revert "Show U+FFFD REPLACEMENT CHARACTER for invalid Unicode codepoints" We now handle U+FFFD replacement in hb_buffer_add_utf*(). Any other manipulation can happen in user callbacks. No need for this. https://github.com/behdad/harfbuzz/commit/efe74214bbb68eaa3d7621e73869b5d58210107e#commitcomment-7039404 This reverts commit efe74214bbb68eaa3d7621e73869b5d58210107e.

7627100f | 2014-07-11 14:54:42 | Mark unsigned integer literals with the u suffix Simplifies hb_in_range() calls as the type can be inferred. The rest is obsessiveness, I admit. | |
|
efe74214 | 2014-07-11 11:59:48 | Show U+FFFD REPLACEMENT CHARACTER for invalid Unicode codepoints Only if the font doesn't support it. Ie, this gives the user to use non-Unicode codepoints as private values and return a meaningful glyph for them. But if it's invalid and font callback doesn't like it, and if font has U+FFFD, show that instead. Font functions that do not want this automatic replacement to happen should return true from get_glyph() if unicode > 0x10FFFF. Replaces https://github.com/behdad/harfbuzz/pull/27 | |

79d1007a | 2013-06-13 19:01:07 | If variation selector is not consumed by cmap, pass it on to GSUB This changes the semantics of get_glyph() callback and expect that callbacks return false if the requested variant is not available, and then we will call them back with variation_selector=0 and will retain the glyph for the selector in the glyph stream. Apparently most Mongolian fonts implement the Mongolian Variation Selectors using GSUB, not cmap. https://bugs.freedesktop.org/show_bug.cgi?id=65258 Note that this doesn't fix the Mongolian shaping yet, because the way that's implemented is that the, say, 'init' feature ligates the letter and the variation-selector. However, since currently the variation selector doesn't have the 'init' mask on, it will not be matched... | |

269de14d | 2013-04-04 23:06:54 | Don't compose Hangul jamo See thread "an issue regarding discrepancy between Korean and Unicode standards" on the mailing list for the rationale. In short: Uniscribe doesn't, so fonts are designed to work without it. | |

6e74c642 | 2013-02-11 06:50:17 | Improve normalization heuristic Before, for most scripts, we were not trying to recompose two characters if the second one had ccc=0. That fails for Myanmar where U+1026 decomposes to U+1025,U+102E, both of which have ccc=0. However, we do want to try to recompose those. We now check whether the second is a mark, using general category instead. At the same time, remove optimization that was conflicting with this. [Let the Ngapi hackfest begin!] | |

eba312c8 | 2012-11-16 12:39:23 | Plumbing to get shape plan and font into complex decompose function So we can handle Sinhala split matras smartly... Coming soon. | |
|
0736915b | 2012-11-13 12:35:35 | [Indic] Decompose Sinhala split matras the way old HarfBuzz / Pango did Had to do some refactoring to make this happen... Under uniscribe bug compatibility mode, we still plit them Uniscrie-style, but Jonathan and I convinced ourselves that there is no harm doing this the Unicode way. This change makes that happen, and unbreaks free Sinhala fonts. | |

b85800f9 | 2012-08-31 18:12:01 | [Indic] Implement dotted-circle insertion for broken clusters No panic, we reeally insert dotted circle when it's absolutely broken. Fixes most of the dotted-circle cases against Uniscribe. (for Devanagari fixes 80% of them, for Khmer 70%; the rest look like Uniscribe being really bogus...) I had to make a decision. Apparently Uniscribe adds one dotted circle to each broken character. I tried that, but that goes wrong easily with split matras. So I made it add only one dotted circle to an entire broken syllable tail. As in: "if there was a dotted circle here, this would have formed a correct cluster." That works better for split stuff, and I like it more. | |
|
f4cb4762 | 2012-08-10 03:51:44 | [OT] Slightly adjust normalizer The change is very subtle. If we have a single-char cluster that decomposes to three or more characters, then try recomposition, in case the farther mark may compose with the base. | |

b00321ea | 2012-08-09 22:33:32 | [OT] Avoid calling get_glyph() twice Essentially move the glyph mapping to normalization process. The effect on Devanagari is small (but observable). Should be more observable in simple text, like ASCII. | |
