Non-ascii chars are rendered incorrectly in one PDF document

[JasnaPaka]

One contributor sent me PDF document where you can see non-ascii chars rendered incorrectly. I think chars like "č", "ř" etc. I don't have problems with different documents. Adobe Reader renders all chars correctly.

PDF document: http://www.jasnapaka.com/bugs/wrong-font.pdf
Pdf.js in Firefox: 30.0a1 (2014-02-10)
OS: Windows 7 64bit

No error or warning in Web Console.

Result in pdf.js: http://jasnapaka.com/bugs/wrong-font-pdf-js.png
Result in Adobe Reader 10.1.9.22: http://jasnapaka.com/bugs/wrong-font-adobe-reader.png

I can reproduce this using Windows 7 x64, Firefox Nightly 30.0a1 (64 bit, HWA on) and the latest PDF.js development version. There are no messages in the console.
