Linux systems utilize font configuration engines like fontconfig to manage, render, and substitute typefaces across different applications. When you type or read Tamil text online, your system looks for specific glyphs mapped to the Tamil Unicode block (U+0B80 to U+0BFF).

Once the installation finishes, the system needs to rebuild its font information cache so running applications can recognize the newly added typefaces. Force a rescan of the font directories by running: sudo fc-cache -fv Use code with caution. Verifying the Installation

If Tamil text still shows up as empty squares or question marks, your application might be overriding system defaults.
