The newpxmath package (version 2013/12/12 v1.061) makes angle brackets vanish from math mode:


  $\langle x \rangle$

This results in just “x” rather than the expected “〈x〉”. Presumably the following messages from the .log file are relevant:

Missing character: There is no h in font zplsy!
Missing character: There is no i in font zplsy!

Can anyone suggest how to get those angle brackets back again, other than reverting to mathpazo?

  • It seems that newpx has already been fixed: the update should be available by tomorrow on TeX Live. I'll test it as soon as I'll install the update. – egreg Jan 8 '14 at 23:25
  • Yep! I reported the problem to Michael Sharpe as @egreg suggested. Within 45 minutes, Michael acknowledged the bug, fixed it, sent me corrected files, and said he'd send the fix to CTAN. Wow! – Ben Liblit Jan 9 '14 at 0:44
  • Good team work! – egreg Jan 9 '14 at 0:48
  • Absolutely. I tip my \hat to both of you! – Ben Liblit Jan 9 '14 at 0:51

It seems that the last update to newpx has introduced a bug: please, report it. For the time being, you can use the corresponding glyphs in newtx:


\DeclareFontFamily{U}{ntxmia}{\skewchar \font=127 }
  <-> \npxmath@scaled ntxmia

  <-> \npxmath@scaled ntxbmia



  $\langle x \rangle$ $\bigl\langle x\bigr\rangle$

The second formula is to show that the bigger symbol is correctly set.

With yesterday's (2014-01-08) release of newpx (version 1.071), the problem has been solved, so the described patch is not necessary any more.
