2018-03-09Explicitly mark helper methods that only operate on ASCII rangesRyan Harrison
A number of our character helper methods take in wide character types, but only do tests/operations on the ASCII range of characters. As a very quick first pass I am renaming all of the foot-gun methods to explictly call out this behaviour, while I do a bigger cleanup/refactor.

2018-02-16Correct mapping text to characters for characters missing from fontRyan Harrison
When parsing text streams there is an internal character list that is generated of all the characters in the stream. Additionally a text string is generated that is exposed via the public API. This string will have all of the printing, i.e. non-control characters, in it. For characters that are not in the font of the stream the unicode, but printable, the character 0xFFFE is used in the text to indicate a missing character. This a non-printing character to indicate non-unicode. The internal character list gets a Unicode value 0x0 when there isn't a glyph in the font for it and the original character code is preserved. This means that when generating the mapping between text string and character list, the code is mistakenly thinking that the unprintable character was not present in the text string. I have changed the check in the mapping generation code to correctly account for this. Additional investigation is needed to determine if inserting 0xFFFE in the text is the correct behaviour. This patch resolves an issue where the find highlights in Chrome for a PDF would be offset when there are unprintable characters in a stream.

2017-11-30Rewrite lower level details of extracting text from pageRyan Harrison
The current implementation of text extraction was difficult to understand, duplicated logic that existed in other methods, and wasn't clear about the units the inputs were in. It also didn't handle control characters correctly. The new implementation leans on the methods for converting indices between the text buffer index and character list index spaces to avoid duplication of code. It also makes it clear to the reader that inputs are in the character list index space. Finally, it fixes issues being seen in Chrome with respect of ranges being slightly off. This CL also adds a test for extracting text that has control characters.
