Found using examples/svgviewer using Windows 7 x64, Firefox 33.0a1 (64-bit, HWA on) and the latest PDF.js development version.

See https://i.imgur.com/xrXkUTL.png for what's happening. This bug has been reported upstream (https://bugzilla.mozilla.org/show_bug.cgi?id=1023929), so this is a tracking bug for the upstream issue.

We can avoid that by specifying non-zero width of the characters in the 'hmtx' table, see https://github.com/mozilla/pdf.js/blob/master/src/core/fonts.js#L4307
