I am filling out this PDF form, IRS Form 1040, in evince 3.36.7 on Ubuntu 20.04 and having a problem that the numbers I input are not aligned correctly with the background bars. Please see this screenshot: Form 1040, DejaVu In the box filled by 123456789, the correct rendering should look like 123|45|6789, but 5 is almost pushed out to the right of the second vertical bar. The spacing between the numbers are much wider than the form creator intended.

It looks that Helvetica LT Std Bold font is assigned to this box, but I don't have this font. Ubuntu substituted it with DejaVu Sans Bold.

I installed MS Core Fonts and changed the substitution with Arial Bold by editing fonts.conf file. However, the spacing did not change. (Screenshot not shown.)

I also tried filling and rendering the form in firefox, chrome, and okular, but they had the same spacing problem.

I think this problem have the same root as the issue reported in these posts.

The issue there has not been resolved for a several years, and it looks difficult to resolve it.

I would like to know any workarounds for this particular PDF form. Is it possible to specify substitution font size (to compensate the too-wide spacing)? Is there a PDF viewer that works? Should I buy the font?

Do Windows and Mac not have this problem? (If so why? Isn't this essentially a problem of fonts? I guess Helvetica LT may not be on so many Windows or Mac computers.) If they work, does wine or virtualbox work?


The fonts used in the PDF are as following. Among them, the fonts for the input fields are Zapf Dingbats, Helvetica, and Helvetica LT Std Bold. I believe the numbers in question is Helvetica LT Std Bold.

A very similar issue was found to be a fontconfig bug, and was fixed in Ubuntu 21.04 and also upstream.

So possibly, on 20.04, it's sufficient to open /etc/fonts/conf.avail/45-latin.conf for editing and add this snippet:

    <family>Courier Std</family>
  • Thank you, but this form does not use Courier. I edited my question and added the full list of fonts in used in the PDF.

  • @norio: Sorry, I didn't read the question carefully enough. But with that said it ought to be some replacement font available which could be specified via fontconfig. Can't tell which one, though. May 3, 2021 at 10:20
  • I tried replacing Helvetica LT with Arial and also with Nimbus Sans, but neither of them worked. I learned that Helvetica is metric-compatible with Arial and Nimbus Sans, and I believe Helvetica LT is essentially the same as Helvetica. So, it looks there is something more than missing-font in this problem. I am suspecting that the social security number box of Form 1040 has a font alignment or spacing specification that is not properly handled by evince or its back-end rendering engine.

One option that might work for you is to grab a copy of the Helvetica .dfont file, convert it to a .ttf, and copy it to your fonts directory.

The gist goes like this:

  1. Install fondu
    sudo apt install fondu
  2. Download the Helvetica.dfont file from this helpful GitHub repository
  3. Convert the font:
    fondu Helvetica.dfont
  4. Open the resulting .ttf using the FontViewer application. This is easiest by double-clicking the font file in Nautilus.
  5. Click the “Install” button in the upper-right corner

Hopefully this will give you a better-spaced font.
