Configuration:

• Web browser and its version: Firefox 47.0 (stable)
• Operating system and its version: OSX 10.11.5
• PDF.js version: pre-shipped version (therefore probably 1.4.121), but also reproduced in 1.5.188
• Is an extension: no

Steps to reproduce the problem:

Three letters from U+11C2C..11C2E are displaced from the original position. The selection is correct, just that glyphs are displaced. It renders correctly in OSX Preview, built-in viewer in Windows Chrome, and SumatraPDF.
