I'm trying to convert an html document with text in multiple languages (utf-8 encoding) to pdf using wkhtmltopdf, and ran into the exact issue described here:

Squared characters issue on wkhtmltopdf

The most popular answers there are to install urw-fonts, which seems to have worked for many people with this issue. But when I search for this package in the Debian apt repository, it doesn't find anything. Someone suggested installing gsfonts-x11, but that didn't fix the issue.

My question is:

Is there a similar/equivalent Debian font package that can be used by wkhtmltopdf to correctly render utf-8 fonts?

Thanks!

    Did you find anything? I'm having this problem too. – Ross The Boss Mar 14 '17 at 16:18
  • @RossTheBoss nope, had to use a workaround by creating an image of the multi-language text and putting that into the document (just saw this comment)). – Yury Oct 17 '18 at 19:56

Getting other languages rendering in wkhtmltopdf:

  1. created a folder: /path/to/downloaded/fonts
  2. create fonts.conf (see below)
/path/to/downloaded/fonts/fonts.conf
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
  <dir>/path/to/downloaded/fonts/</dir>
  <cachedir>/tmp/fonts-cache/</cachedir>
  <config></config>
</fontconfig>

  1. downloaded Google's Noto fonts into /var/task/fonts. For each language you need, you can download its associated language ttf files.

  2. Set your ENV variables: FONT_CONFIG_PATH=/path/to/downloaded/fonts/ and FONTCONFIG_FILE=/path/to/downloaded/fonts/fonts.conf

  3. In the target HTML file, set the meta tag in the head of the document: 

<head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
</head>

You may find that you need to add additional fonts, but they are found on the the Google Noto Site. I used all the *-regular.ttf files to keep my container smaller.

If you happen to be doing this in AWS / amazonlinux2, you also need to set: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/wkhtmltopdf; You can confirm that the libaries are mapped correctly with: ldd /path/to/wkhtmltopdf Your result should look like this:

        linux-vdso.so.1 (0x00007ffc7f5cf000)
        libXrender.so.1 => /var/task/lib/libXrender.so.1 (0x00007f1ea6db1000)

        linux-vdso.so.1 (0x00007ffce59b0000)

If the path is wrong, it'll look like this:
