text selection omits letters about sumatrapdf HOT 4 CLOSED

Technically you have 11 lines of spaced out text, these can be concatenated into one line

You have a point, but the pdf file you attached has the same problem, the last letter "d" is not selected either

The size of a selection is a guess based on a nominal spacing as there is no clue other that what the writer provides, I accepted the given values which will be computed by MuPDF (and its font reading dependencies)
The permutations for such a placement amounts to thousands of possibilities, since the letters can be placed in any order and still be counted as one word that contains a space character or more.
If I switch the font to MS Windows Arial it works

However playing around with those values in the original, it does look like total width calculated is less than visible placements. so perhaps there is some oddity in the MuPDF assessment of PS Arial character widths. It would need to be compared with MuPDF reader to see which one is reducing (not increasing) the selection, but basically the custom font is either not providing/or not read as correct widths .

Ah, I wasn't aware that Sumatra is based on MuPDF. Just tried it, and it shows same issue. I shall try to talk to MuPDF dev then -- thank you!
