St Josephs Hill park map has a bogus Õ character in title

[dholbert]

This PDF...
http://www.openspace.org/preserves/maps/pr_st_josephs.pdf
...renders with a weird "Õ" character in the title, in PDF.js.

This bogus character isn't shown in Evince or xpdf.

This affects the version of PDF.js currently shipped with Firefox Nightly, as well as the development version at http://mozilla.github.com/pdf.js/extensions/firefox/pdf.js.xpi (which reports itself as being version 0.8.845)

I can replicate this using Windows 7 x64, Firefox 26.0 (HWA on) and the latest PDF.js development version. There are no console warnings/errors.

The PDF file actually contains the Õ (O-tilde) character (I assume that the author intended it to be an apostrophe instead). This can be seen if you open the file in Adobe Reader, and then copy the title and paste it into e.g. a text editor.

The issue here is that the character shouldn't be rendered, because of various properties of the font data in the PDF file, but we currently don't handle this edge case correctly.

I've attempted to write a patch for this, but it doesn't currently make any sense to submit a PR since it would clash with the nice re-factoring being done in #4259. (Also, after that PR, the solution I attempted wouldn't work anyway.)

The PDF has been updated (does not match the screenshot anymore). Closing as fixed for now because there is no reference PDF anymore to test with. If anyone has a similar case that is still broken, we can reopen this.
