Why Bamini or FM text looks wrong on WhatsApp and Facebook
You copy Tamil or Sinhala text from a design file, paste it into WhatsApp or Facebook, and it turns into English letters. The text hasn't been damaged. It is just in an old font that these apps don't know.
Why it happens
WhatsApp, Facebook, Instagram, Gmail and websites all use Unicode. Bamini, STMZH and FM text is only readable when the matching font is on the device. Your friends don't have it, so they see English letters.
The fix
- Convert the text to Unicode with the right tool: Bamini, STMZH or FM Abhaya.
- Copy the result.
- Paste it into the app. Everyone will see proper Tamil or Sinhala.
Posts and captions made in a design program
If you design a poster in a legacy font, export it as an image for social media. A picture looks the same on every phone. Keep a Unicode version of the words for the caption, so that people can search and copy it.
