Hello,

I am confronted with difficulties to understand why do I get this strage error then compile the attached document? And how to fix it?

! String contains an invalid utf-8 sequence. l.1 \setuppublicationlist[samplesize={ ─A},totalnumber=1]

Bibtex doesn't support utf-8 at all, which is why it breaks breaks up the Č into two bytes, and then only uses the leading byte in the samplesize. A working workaround is tu use {\Ccaron} in the bib file instead of the literal character. Best wishes, Taco
