Currently if a font contains a `toUnicode` entry, we always create a new `ToUnicodeMap` in evaluator.js. This is done even for `IdentityV/IdentityH`, despite to possibility to use the much more compact `IdentityToUnicodeMap` representation. This patch refactors the `IdentityH/IdentityV` cases, to: - Avoid calling `IdentityCMap.getMap`, since this prevents allocating and iterating through an array with 65536 elements. - Ensure that the handling of `toUnicode` is actually correct in fonts.js. We rely on `toUnicode instanceof IdentityToUnicodeMap` in a few places, and currently this does not work correctly for `IdentityH/IdentityV`. |
