Due to the way emoji ZWJ sequences are defined, the ICU line breaking algorithm determines that there are valid line breaks inside the sequence. This patch suppresses these line breaks. This is an adaptation of I225ebebc0f4186e4b8f48fee399c4a62b3f0218a into the nyc-dev branch. Bug: 25433289 Change-Id: I84b50b1e6ef13d436965eab389659d02a30d100f

In cases when a word (as defined by the ICU break iterator) overlaps a style boundary, the returned wordStart can be extend before the range currently being measured for layout. When we try to hyphenate the resulting substrings, we get a negative range, which crashes. This patch disables hyphenation in this case.

Recent changes have added special cases for line breaks within URLs and email addresses. Such breaks are undesirable when they can be avoided, but at other times are needed to avoid huge gaps, or indeed to make the line fit at all. This patch assigns a penalty for such breaks, equal to the hyphenation penalty. The mechanism is currently very simple, but would be easy to fine-tune based on more detailed information about break quality.

This change adds accceptable line breaks according to sections 7.42 (Dividing URLs and e-mail addresses) and 14.12 (URLs or DOIs and line breaks) of the Chicago Manual of Style (16th ed.). In general, these place breaks before punctuation symbols, and suppresses them after hyphens. Bug: 20126487 Bug: 20566159 Change-Id: I2d07d516b920a506a2f718c38fb435c5eb1ee1f8

Before this patch, the font fallback chain iterated all installed font families if a variation selector was specified. This CL narrows down the range of iteration. To decide the font family for the variation sequence, we need to search for both the variation sequence and its base code point. The new range of the iteration is a union of them. With this change, the running time of Paint.hasGlyph for the variation sequence improves 50% and the running time of Paint.measureText for the variation sequence improves 40% for the large text case on Nexus 6 userdebug.

Implement a WordBreaker that defines our concept of valid word boundaries, customizing the ICU behavior. Currently, we suppress line breaks at soft hyphens (these are handled specially). Also, the new WordBreaker class has methods that determine the start and end of the word (punctuation stripped) for the purpose of hyphenation. This patch, in its current form, doesn't handle email addresses and URLs specially, but the WordBreaker class is the correct place to do so. Also, special case handling of hyphens and dashes is still done in LineBreaker, but all of that should be moved to WordBreaker.

It turned out that hb_font_t creation is not a lightweight operation. Especially, Paint.hasGlyph creates hb_font_t for all existing fonts every time. To improve the performance, cache hb_font_t instead of hb_face_t. Note that to calculate horizontal advance, MinikinPaint needs to be associated with hb_font_t by calling hb_font_set_funcs. With this patch, hb_font_set_funcs may be called multiple times for the same hb_font_t object. However this is not an issue since MinikinPaint is unique during layout.

Bug: http://b/26781196 Bug: http://b/25884483 Bug: http://b/26432628 Although this issue was first only manifesting on Fugu, it now affects N9 and N6p as well. This change disables unsigned overflow sanitization on all platforms. The real fix for libc++ (r257368) can't be committed until we have updated Clang at least one more time.

The motivation of this CL is enhance the font fallback score design to support multiple language font fallback. This CL contains following changes: - Break language based font score into two: script-based score and primary-language-based score. - The primary-language-based score is 0 if the script-based score is 0. If the script-based score is not 0 and the primary language is the as same as the requested one, the font gets an extra score of 1. - The language score gets a higher multiplier for languages higher in the locale list.
