Bug - Tamil letters ப் and வ் causing problems in viewer

Development
1

Hi,

  1. When I write ப் in editor at the beginning of a line, it shows as undefined character in the viewer, together with the rest of Tamil symbols I write in that line until I use for ex. a Latin letter, then it shows Tamil letters which follow.

  2. When I write a single letter வ் at the beginning of a line, it also shows as an undefined character in the viewer

In the beginning I had same problems also in the editor, until I have set "Noto Sans Tamil" font in the "Editor font family" (Appearance Options).

D.

At present, Joplin doesn't have a built-in setting for the Markdown viewer font family.

Here are two possible workarounds:

Additional info regarding Tamil font rendering issue – resolved in tables via userstyle.css

Hi everyone,

Just wanted to share an additional update regarding the Tamil font rendering issue.

I was able to resolve the issue on the Android app using the Extra Markdown viewer plugin, and Tamil text displays correctly there now.

However, I was still facing issues on the Desktop app, specifically when Tamil text appeared inside Markdown tables. The rest of the text rendered fine, but inside tables, characters like ப and வ were still showing as tofu (□).

After some trial and error, I fixed the issue by adding the following CSS to the custom stylesheet for rendered Markdown:

Tools → Options → Appearance → Show Advanced Settings → Custom stylesheet for rendered Markdown (userstyle.css)

/* For styling the rendered Markdown */

body {
  font-family: "Noto Sans Tamil", sans-serif !important;
}

table {
  font-family: "Noto Sans Tamil", sans-serif;
}

table td, table th {
  font-family: "Noto Sans Tamil", sans-serif;
}

After applying this, the Tamil font is now rendered correctly in tables as well.

Hope this helps anyone facing similar issues – and perhaps this can be considered for a more integrated solution in the future.

Thanks!
