[tex-live] tu-clash

[Bob Tennent]

I'm getting the following when I try to use xelatex (or
lualatex):

  (/usr/local/texlive/2016/texmf-dist/tex/latex/fontspec/fontspec-xetex.sty
  *************************************************
  * fontspec warning: "tu-clash"
  * 
  * I have found the tuenc.def encoding definition file but the TU encoding is
  * not defined by the LaTeX2e kernel; attempting to correct but you really
  * should update to the latest version of LaTeX2e.
  *************************************************
  (/usr/local/texlive/2016/texmf-dist/tex/latex/base/fontenc.sty
  (/usr/local/texlive/2016/texmf-dist/tex/latex/base/tuenc.def
  ! Missing \endcsname inserted.
  <to be read again> 
                     \def 
  l.252 ...           \UnicodeEncodingName {}{"007E}

AFAIK, I'm fully updated.
