Convert UTF8 encoded passwords to ISO-8859-1 for |R = 6| encryption (issue 6010)

For passwords where the encoding already is correct, the conversion is a no-op.
Also, since `encodeURIComponent` might throw, we need to make sure that we handle that case too.

Fall back to the |defaultEncoding| when no valid "post" table is found in TrueType fonts (bug 1050040)
...
Fixes https://bugzilla.mozilla.org/show_bug.cgi?id=1050040 .
With this patch the file is completely readable, but given that the font is broken enough to be rejected by OTS the rendering differs slightly from Adobe Reader.
*Note:* the PDF file is sufficiently broken that even Adobe Reader complains about the font, *and* also about another more general issue.

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.

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.

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.
