Jonas Jenwald	4c2ad3bc7b	Ensure that entries in the Differences array of Type1 fonts are either numbers or names This patch is yet another installment in the (never ending) series of bugs in PDF files with non-embedded fonts. Fixes http://www.int.washington.edu/talks/WorkShops/int_08_37W/People/Franz_M/Franz.pdf.	10 years ago
Jonas Jenwald	fda858ae33	Don't map glyphs to certain problematic General Punctuation Unicode locations (bug 911034) Fixes the remaining missing characters in https://bugzilla.mozilla.org/show_bug.cgi?id=911034. For reference, see http://www.unicode.org/charts/PDF/U2000.pdf (and also http://en.wikipedia.org/wiki/General_Punctuation_%28Unicode_block%29).	10 years ago
Jonas Jenwald	2b1a13ba28	Don't map glyphs to Unicode position 0x0E33, i.e. Thai character SARA AM (bug1046314) A similar approach as in PR 5705. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1046314. According to https://dxr.mozilla.org/mozilla-central/source/gfx/harfbuzz/src/hb-ot-shape-complex-thai.cc#270-365, `0x0E33` is treated as a special case (by the font shaping code in Firefox). Hence it seems reasonable to skip it when adjusting the font mapping.	10 years ago

Jonas Jenwald	f81fc9091a	Correctly detect OpenType font files with CFF data Fixes 5334. Fixes 215. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1125614. According to the specification, http://www.microsoft.com/typography/otspec/otff.htm, OpenType font files with CFF data should have `OTTO` in the header.	10 years ago
Jonas Jenwald	0a3341dadc	Don't map glyphs to Unicode "Dotted circle" combining mark (bug 1108301) It seems that `0x25CC` is another bad spot for charCodes. Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1108301.	10 years ago

Jonas Jenwald	417800a1b5	Only skip the \|!isSymbolicFont\| check for TrueType (3, 1) cmap tables if no previous cmap table was found (PR 5703 followup) Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=894572.	10 years ago

Jonas Jenwald	01e6565dd4	Try to skip mapping of missing TrueType glyphs Also don't skip mapping of glyphs which are empty, if the corresponding charCode is included in toUnicode.	10 years ago
Jonas Jenwald	8174da61fb	Don't skip mapping of glyphs for CIDFontType2 fonts with a CIDToGIDMap Also don't skip mapping of glyphs which are empty, if the corresponding charCode is included in toUnicode.	10 years ago
Jonas Jenwald	ad41a2d574	Add support for TrueType (0, 0) cmap tables (issue 5501 and 5574)	10 years ago
Jonas Jenwald	1fea44ce14	Ensure that \|get fingerprint\| doesn't fail if the ID is not an array (issue 5599) According to the [PDF specification](http://www.adobe.com/content/dam/Adobe/en/devnet/acrobat/pdfs/PDF32000_2008.pdf#page=51) the `ID` should be an array. To prevent errors if the PDF file violates that part of the spec, check that the `ID` is actually an array. Fixes 5599.	10 years ago
Jonas Jenwald	75767abb09	Add a reduced test case for issue 4379 This should have been part of PR 5136. Based on comments https://github.com/mozilla/pdf.js/issues/4379#issuecomment-51221787 and https://github.com/mozilla/pdf.js/issues/4379#issuecomment-51475463, it should be OK to include the PDF file in the repo.	10 years ago
Jonas Jenwald	d8b905048b	Add fallback for non-embedded "Century Gothic" CIDFontType2 font (issue 4722 and bug 879561) According to practical experiments, falling back to "Helvetica" when we encounter a non-embedded "[Century Gothic](http://en.wikipedia.org/wiki/Century_Gothic)" `CIDFontType2` font seems to work well. (Also, the section on Wikipedia about "Printer ink usage" might provide some anecdotal evidence that Century Gothic is a fairly standard sans-serif font.) Obviously this patch doesn't make "Century Gothic" fonts render perfectly, as is often the case with non-embedded fonts, but all the text is now legible in the referenced issues. Fixes 4722.

Jonas Jenwald	26f5b1b2d3	Add a couple of reduced test-cases for PR 4259 PR 4259 fixed a large number of font bugs, but none of those where added as test-cases. This was, in my opinion, unfortunate since it increases the risk of regressions in the future when other font bugs are fixed. This PR simply adds a few more test-cases, to improve our test coverage somewhat.	11 years ago
