I recently updated to TexLive 2016 (specifically MacTex 2016) from TexLive 2015 and, without changing any source code, the output of a document changed with XeLaTeX. Specifically, bold math italic became bold math (not italic) and some uppercase bold math italic fonts became blank spaces. I am using

\unimathsetup{math-style=ISO, bold-style=ISO, sans-style=italic}

and the problem arises with both minion math and lucida OTF math fonts (possibly others, these are the only ones I tried) when using \mathbf{u = \Omega}. I can provide more details - a full MWE if needed - but I wondered first if this was a known issue? Or perhaps my way of calling the routines is deprecated.

  • I think unicode-math underwent a big change a little while ago that changed a lot of how different font styles are applied/used. You could have a look at the manual for the latest version of unicode-math, and see if any of what you're doing conflicts with what is described there. – Torbjørn T. Oct 5 '16 at 10:32
  • I think river-valley.zeeba.tv/… is where I heard of it by the way. – Torbjørn T. Oct 5 '16 at 10:34
  • The unicode-math manual (the one that pops up with texdoc unicode-math) looks to be the same as before. It is dated June 2014 and has the same calling parameters. – GeoffV Oct 5 '16 at 10:36
  • Add \listfiles to your file (before \documentclass) and check the list of packages that are added to the end of the .log file to see which version is actually used. In my TL2016 I have v0.8c of unicode-math dated September 2015. – Torbjørn T. Oct 5 '16 at 10:38
  • Sorry, I meant September 2015 in my previous comment. However, the calling method seems to be the same with the new version, and in particular \unimathsetup{math-style=ISO, bold-style=ISO} still appears to be supported. I will look more closely though to see if anything else has changed, thanks for that suggestion. – GeoffV Oct 5 '16 at 10:51
