[NTG-context] Strange spurious character

Hi Hans, After having updated my installation of ConTeXt, I noticed the presence of a spurious « ß » character at the top of every document, or sometimes in the footer, or in the header. Also in the example below the text is typeset with bold italic, even though there is no request for it. Here is a minimal example: %%%% begin bug-beta.tex \definefallbackfamily[mainface][serif][palatino] \definefontfamily[mainface][sans][palatino] \setupbodyfont[mainface] \starttext Why is there a « ß » LATIN SMALL LETTER SHARP S above? Why is the text in bold italic? \stoptext %%%% end bug-beta.tex Best regards: OK
