When a run has no cmap coverage in any font, use the base font. Most of the time, this will cause rendering of the .notdef glyph, which is preferable to displaying nothing. In some cases, Harfbuzz may be able to decompose the characters (not in the cmap) to ones that are, in which case we'll render those, as long as they're in the base font.

Proper Japanese layout requires sophisticated rules for spacing punctuation, not just turning on the "palt" (proportional alternate) feature. Until we can support the whole set, roll back palt. Change-Id: If2359c529b70b1dd45dddc00e5f4aa1c91f8b0e9

This patch includes an implementation of grapheme cluster breaking, which is especially useful for repositioning the cursor for left and right arrow key presses. The implementation is closely based on Unicode TR29, and uses the ICU grapheme cluster break property, but is tailored to more closely match the existing implementation and expected behavior. Part of a fix for b/15653110 Improve behavior of arrow keys in EditText Change-Id: I8eb742f77039c9ab7b2838285018cf8a8fc88343

Fixes b/15734816 In the text "Wi-Fi", "-Fi" appears bolder than "Wi" The problem was caused by "stickiness" in choosing fonts, where layout would prefer using a font used for preceding characters as long as it mapped the following characters in a run, in favor of the "best match" rules. This patch adds a whitelist for making the stickiness more conservative, only applying it for characters necessary for correct shaping (ZWJ and ZWNJ in particular) and basic punctuation, where it is desirable to match the style of the preceding text.

We want to test configurations where the Noto Japanese font will have its "palt" feature (to select tighter spacing in kana) will be enabled for framework but not WebView or Chrome rendering of Japanese text. This patch simply hardcodes this feature on. This is also a first step towards more general setting of OpenType features. The hardcoded feature list will grow into one set by parameters which will eventually be plumbed up to Java. Change-Id: Ie284e0487a1434155c8ac1cb68ddc4fc4b3c018a

This is a fix for bug 15185229 ZWJ not working in Sinhala and Kannada. Indic fonts (unlike Arabic) require the entire string, including ZWJ, to be passed to Harfbuzz; it's not enough for the ZWJ to be present in the context. The solution is to be "sticky" in font itemization, continuing to use the same font as long as it has Unicode coverage. Change-Id: I7673bc56fbda09f1e1a4582e8d88342343b706f1

This patch adds a "lang" pseudo-CSS property and uses it both to select an appropriate font and control the "locl" OpenType feature to get the most appropriate rendering for the langauge and script. In addition, the "-minikin-variant" property selects between "compact" and "elegant" variants of a font, as the former is needed for vertically cramped spaces.

This patch adds caching for both layouts and for HarfBuzz face objects. The granularity of the cache for layouts is words, so it splits the input string at word boundaries (using a heuristic). There are is also some refactoring to reduce the amount of allocation and copying, and movement towards properly supporting contexts. The size of the caches is a fixed number of entries; thus, it is possible to consume a large amount of memory by filling the cache with lots of large strings. This should be refined towards a scheme that bounds the total memory used by the cache. This patch fixes bug 15237293 "Regression: Measure performance is significantly slower with minikin".

This is a fix for bug 15130102 "Language name for Hebrew displayed the wrong way around on keyboard". This patch extends the previous BiDi support (when the direction for the entire string was given by the caller) to run the BiDi algorithm (provided by ICU) over the string to break it into BiDi runs. Thus, it handles mixed LTR and RTL strings in a single layout, and also respects heuristics for inferring the paragraph direction from the string.

This patch contains a very basic implementation of BiDi. It respects the BiDi flags passed in as an explicit parameter (through the "-minikin-bidi" pseudo-CSS property), but doesn't yet do its own BiDi run detection. It also takes some shortcuts (marked as TODO) that are based on reasonable assumptions of the current font stack, but not universally valid. Even with these shortcomings, it seems to display RTL text from TextView correctly. Change-Id: I223433923c4eb06f90c0327e86bfbe0aff71d4f5

This patch improves script run itemization and also exposes metrics and bounds for layouts. In addition, there is a fair amount of internal cleanup, including ref counting, and making the MinikinFont abstraction strong enough to support both FreeType and Skia implementations. There is also a sample implementation using Skia, in the sample directory. As part of its functionality, his patch measures the bounds of the layout and gives access through Layout::GetBounds(). The corresponding method is not implemented in the FreeType-only implementation of MinikinFont, so that will probably have to be fixed. Change-Id: Ib1a3fe9d7c90519ac651fb4aa957848e4bb758ec
