2018-08-28Handle non-printing characters at beginning of extraction regionRyan Harrison
Currently if a text extraction region begins on a non-printing character then "" will be returned. This is the incorrect behaviour, instead the call should scan ahead until a printing character is found and start extracting from there. Also proactively adds a similar check and scan for the end of the extraction region.

2018-08-22Properly handle language markers in decoded textRyan Harrison
In text like document title 0x001B is used as a marker for the beginning/end of a language metadata section. Currently PDFium does nothing with this data, but when returning the 'decoded' text it needs to be stripped out. The existing code assumed that the two bytes following a marker would be the data to be removed and did nothing to track if it was in/out of one of these regions. This led to a situation where it would always strip the two bytes following the region, since it assumed the end marker was the beginning of a new region. This CL corrects the detection and handling of these regions, and adds a regression test for the reported bug.

2018-08-08Move ByteString::FromUnicode() to WideString::ToDefANSI()Tom Sepez
Turns out that "FromUnicode" is misleading in that, on linux, it simply removes any characters beyond 0xFF and passes the rest unchanged, so no unicode decoding actually takes place. On Windows, it passes it into the system function specifying FX_CODEPAGE_DefANSI, converting it into the so-called "default ANSI code plane", passing some characters, converting others to '?' and still others to 'A'. Either way, nothing resembling UTF8 comes out of this, so pick a better name. These now immediately look suspicious, so a follow-up CL will see which ones should really be WideString::UTF8Encode() instead. Making this a normal method on a widestring rather than a static method on a bytestring feels more natural; this is parallel to the UTF8Encode and UTF16LE_Encode functions. Add a test that shows these conversions.
