This CL contains the following changes: - Add a variation selector argument into getFamilyForChar to be able to select fonts which support variation selector. - In case no fonts support the codepoint and variation selector pair, add a fallback rule which selects font family with ignoring variation selector. - Change FontCollection::itemize to not change the font family immediately preceding a variation selector. - Introduce unit tests for variation selectors. With this CL, TextView can render the variation selectors correctly. Bug: 11256006 Change-Id: I22ce0e9eadc941f84e3a9b23462f194e51dd7180
