I tried to debug this, but it looks very strange. The cmap looks like this:
311 0 obj
<</Length 294>>stream
/CIDInit /ProcSet findresource begin
12 dict begin
begincmap
/CMapType 2 def
/CMapName/R857 def
1 begincodespacerange
<0000><ffff>
endcodespacerange
3 beginbfrange
<000f><000f><2022>
<0066><0066><007b>
<0067><0067><007d>
endbfrange
endcmap
CMapName currentdict /CMap defineresource pop
end end
endstream
endobj
From reading of pdf spec I can say that bfrange syntax is valid.
parseCMap1() function that calls error() is in poppler. The code there
looks like this:
if (!strcmp(tok3, "[")) {
....
} else if (tok3[0] == '<' && tok3[n3 - 1] == '>') {
....
} else {
error(-1, "Illegal entry in bfrange block in ToUnicode CMap");
}
On call to error gdb shows:
(gdb) print (char *)tok3
$15 = 0x7fffda543fc0 "<007d>"
(gdb) print n3
$16 = 6
(gdb) print tok3[n3-1]
$18 = 62 '>'
(gdb) print (tok3[0] == '<' && tok3[n3 - 1] == '>')
$19 = true
Now if anyone can tell me why branch with call to error() is executed
instead of previous one...
