[NTG-context] issue with font

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
