Created attachment 108731 [details] patch to poppler library Hello, I want to open this bug from gnome Evince users who asked the following thing: distinguish ordinal characters during text search. Here are the characters: 0x207F=ⁿ,0x00AA=ª,0xBA=º,0xB9=¹,0xB2=² ,0xB3=³,0x2074=⁴,0x2075=⁵,0x2076=⁶,0x2077=⁷,0x2078=⁸,0x2079=⁹,.. Besides, these ones are considered like their standard numeric figure, for example º=0, ª =a, that work up false search result with too many characters. This bug has been opened in gnome bugzilla (see bug #429985), this issue has been veted and the conclusion of our search is the following: These characters are replaced because of normalization compatibility decomposition applying on characters strings in poppler library. Here is the solution that i propose: exclude ordinal characters from NFKC normalization as indicated in my patch. Perhaps it could be better to create a fonction to exclude a character from normalization process getting its unicode code point as a parameter. That would allow easy configuration for poppler library users. I hope it helps. Thanks for your excellent work, Frederic Gnome Software Contributor
