Unicode accents (#992)

Browse Source

* Unicode accents

* Lexer now looks for combining dicritical marks and adds them to the same character
* Parser's `parseSymbol` now recognizes both combined and uncombined forms of Unicode accents, and builds accent objects just like the accent functions
* Added CJK support to math mode (not just text mode)

* Add invalid combining character test

* Add MathML test

* Add weak support for other Latin-1 characters

This maintains backwards compatibility, but it uses the wrong font.
There's a TODO to fix this later.

Also refactor symbol code to use for..of

* Update Unicode screenshot

* Remove dot from accented i and j (in math mode)

Also add dotless Unicode characters to support some accented i's and j's

* Fix \imath, \jmath, \pounds, and more tests

* Switch from for..of to .split().forEach()

Save around 800 bytes in minified code

* Fix split

* normalize() detection

* Convert back to vanilla for loops

* Fix merge

* Move normalize dependency to unicodeMake.js

* Make unicodeSymbols into a lookup table instead of macros

This is important for multi-accented characters.

* Add comments about when to run

* Move symbols definition into unicodeMake/Symbols.js

* Remove CJK support in text mode

* Add missing semicolon

* Refactor unicodeAccents to its own file

* Dotless i/j support in text mode

* Remove excess character mappings

* Fix Åå in math mode (still via Times)

* Update to support #1030

* Add accented Greek letter support (for supported Greek symbols)

* Update screenshot

* remove Æ, æ, Ø, ø, and ß from math mode test
