[lltx] no µ in UMTypewriter?

[Reinhard Kotucha]

Hi,
when I compile this file with lualatex

------------------------------
\documentclass[12pt]{minimal}
\usepackage{fontspec}

\begin{document}
\setmonofont{LatinModern Mono}
\texttt{-Ω-µ-}

\setmonofont{UMTypewriter}
\texttt{-Ω-µ-}
\end{document}
------------------------------

there is no µ in the second line (UMTypewriter) in the output.

Is this problem caused by LaTeX support files or is something wrong
with the font itself?  There is obviously a "mu" in the font.
>From the CFF table:

  <CharString name="mu">
    -6 88 -87 66 380 -20 hstemhm
    35 64 237 64 hintmask 01111000
    218 -5 rmoveto
    89 0 33 67 7 0 rrcurveto
    hintmask 10111000
    -4 23 -64 60 34 26 26 34 vhcurveto
    [... stuff omitted ...]
    248 vlineto
    34 -31 43 -20 42 0 rrcurveto
    endchar
  </CharString>

Regards,
  Reinhard
