Please note that the `glyphlist.js` and `unicode.js` files are converted to CommonJS modules instead, since Babel cannot handle files that large and they are thus excluded from transpilation.
Please see http://eslint.org/docs/rules/object-shorthand.
For the most part, these changes are of the search-and-replace kind, and the previously enabled `no-undef` rule should complement the tests in helping ensure that no stupid errors crept into to the patch.
For Arabic characters, the Unicode character codes are mapped to Unicode
character types using the character codes for indexing. However, the
character code 0x061D is undefined (and therefore invalid) in the
Unicode standard. The imported list does not contain this entry, but not
having it in the list breaks indexing for items after it. Therefore, put
an empty string on its position to make indexing work properly and issue
a warning in the unlikely event that we encounter this character.
This lets the JS engine resize the array elements buffer immediately,
thus avoiding some intermediate resizings. This can save multiple MiBs
of reallocation in text-heavy files.
