[NTG-context] issue with font

[Pablo Rodriguez]

Hans,

I have the following sample.

  \starttext
  \definedfont[TruetypewriterPolyglott-mELa.ttf]
  \input zapf
  \stoptext

I get a fatal error in the font file (both LMTX and MkIV).

Font is https://www.fontspace.com/truetypewriter-polyglott-font-f14955
(direct donwnload from https://www.fontspace.com/get/family/zmmx1)

I don’t know what is wrong in the font, but it would be great to be able
to use it with ConTeXt.

Many thanks for your help,

Pablo
