faulty to unicode mapping of chars encoded with surrogate pairs?
when I compile the following with context \pdfvariable compresslevel=0 \starttext $f$ \stoptext I get in the pdf 1 beginbfchar <0515> <D875DC53> endbfchar D875DC53 is according to http://www.russellcottrell.com/greek/utilities/surrogatepaircalculator.htm the codepoint 2D453 and this is not a valid unicode point. As a result copy& paste doesn't work correctly. A similar example with xelatex writes D835DC53 (remark the 3 instead of the 7) instead in the pdf which gives the correct code point 1D453 and copies fine. lualatex gives the faulty value too. -- Ulrike Fischer http://www.troubleshooting-tex.de/
