Created attachment 112107 Remove combining characters from normalized text This patch changes normalization so that combining characters are removed from the normalized text. This makes searching through TextPage::findText insensitive to these characters.
Also, renames unicodeNormalizeNFKC to unicodeNormalizeSearch to make it clear it's no longer doing a regular NFKC normalization. Renames decomp_compat to decomp_compat_base because it now strips combing characters, leaving only base characters, in addition to compatibility decomposition. Removes UnicodeCompTables.h and some compose functions. They're no longer needed since we're not recomposing the characters. I'm not sure if UnicodeTypeTable.h and UnicodeCompTables.h are considered part of the public interface. They're included in the xpdf headers. Albert, is it OK to change these files in this way? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/116453 Title: evince can not find ü in attached PDF Status in Poppler: Confirmed Status in poppler package in Ubuntu: Triaged Bug description: Binary package hint: evince 1) lsb_release -rd Description: Ubuntu Vivid Vervet (development branch) Release: 15.04 2) apt-cache policy evince evince: Installed: 3.14.1-0ubuntu1 Candidate: 3.14.1-0ubuntu1 Version table: *** 3.14.1-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages 100 /var/lib/dpkg/status 3) What is expected to happen with the attached document is when one searches for: über it is found: https://bugs.launchpad.net/ubuntu/+source/poppler/+bug/116453/+attachment/102979/+files/example.pdf 4) What happens instead is it does not return any matches.
