LuaTeX has problems with certain unicode characters SOLVED

[Bernd]

I realized that I did not check "Use no TeX fonts". I think the T1
encoding messes everything up.

Checked it and now everything runs smooth, in LuaTeX and in XeTeX.

Kind regards,

Bernd

But with a font such as Calibri, which has an extensive set of Unicode glyphs, it compiles into a correct pdf.
