Public bug reported:

What I expected to happen:

I am filling out the SS-5 Social Security Administration form (see
attached). I entered "John Jacob Smith" into the "First", "Full Middle
Name", and "Last" fields on page 5.

What happened instead:

I can enter the text without issue, but some of the letters are wrongly
positioned, i.e. the kerning is wrong. For example, the letter "i"
overlaps with the letter "m" in "Smith" (see attached image). It looks
like the font in the fields might be displaying a variable width font
when it is supposed to be a fixed-wdith font.

Discussion:

Since this bug is also present in xpdf and Okular (but not mupdf), I'm
guessing this isn't a bug in Evince itself. However, I am reporting it
here as a courtesy to other users (since Evince is the default PDF
reader) and because I'm not sure which a dependency is responsible. (I'm
also not sure if it's a direct dependency problem or if it's something
else like a fontconfig issue.)

Here is the output for pdffonts ss-5.pdf:

I asked about this in an Ask Ubuntu question nearly a year ago, but
received no response, so I am reporting a bug now instead:
