The appearance of letterspacing with scripts with cursive connections is poor, so we simply disable letterspacing for those scripts. There may be some cases where some form of letterspacing is desirable, but this gives the highest likelihood that the final result will be good without requiring additional work from clients.

Previously, we just assumed the font in use had a U+2010 HYPHEN character, resulting in a tofu (or an empty space) being shown when U+2010 was not supported in the font used to render the hyphenated word. Now we try to fallback to U+002D HYPHEN-MINUS, which has a very good chance of being available in at least any Latin font. We still show a tofu when neither character is supported, to intentionally alert that something is missing.

This patch adds a LineBreaker class to Minikin, which will be used for computing line breaks in StaticLayout. The version in this patch contains basically the same functionality that existed before, but hopefully better performance and an interface that's suitable for more sophisticated paragraph layout. Note that this version contains a high quality strategy, which mostly works but doesn't respect varying line width. Change-Id: I02485d58b1e52856296a72cdd4efd963bc572933

Previously, HarfBuzz's default fallback to compatibility decompositions resulted in Mathematical Alphanumeric Symbols getting rendered as normal letters and digits when there was no font available to render them. This patch disables that fallback, to ensure they are displayed as tofus. Based on a patch by Behdad Esfahbod. Bug: 19202569 Change-Id: I357f172302448d4ab0b24efc86119f1977b5996b

Fractional advance widths were causing subtle problems with text positioning when the same text was drawn with different spans in the hwui renderer. Quantizing the coordinates on layout (as opposed to waiting until the renderer draws the glyphs) solves the problem. This patch also fixes a discrepancy between x position and advance widths when letterspacing. Bug: 17347779 Change-Id: Ia705944047408c2839d5ad078eefd6bbec446872

C++ local var initialization always tricks me. Previously, Layout didn't have a constructor, which meant that defining it on the stack left mAdvance uninitialized. This was not an issue when we were doing "new Layout()", since that invokes zero-initialization, but was an issue for the skipCache path that was allocating layout on stack by just "Layout l" instead of "Layout l = Layout()". To avoid surprises, add a constructors that clears everything. Also adds reset() method to reset the layout for reuse. Change-Id: I3e02f00da9dd7d360abe13f63c310f6882292d0a

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 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 is part of the fix for bug 15179652 "Japanese font isn't shown on LMP". Change-Id: I7fab23c12d4c797a6d339a16e497b79a3afe9df1

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
