Regression: Amharic (Ethiopic) text rendering broken in Telegram Desktop 6.4.2 (worked in 5.x–6.1)

[lejteddy-max]

Steps to reproduce

1. Install Telegram Desktop 6.4.2
2. Open any chat containing Amharic (Ethiopic) text
3. Observe incorrect rendering (broken glyphs / missing characters)

Expected behaviour

Amharic (Ethiopic) text should render correctly, as it did in Telegram Desktop 5.x – 6.1.

Actual behaviour

Amharic text renders incorrectly or unreadably.
Looks like font fallback or shaping is broken.

Operating system

Version of Telegram Desktop

Additional notes / suspicion

This appears to be related to a font fallback or text shaping issue for Ethiopic (Amharic) script in Telegram Desktop 6.4.2.

In previous versions (5.x – 6.1), Amharic text rendered correctly on the same system. In 6.4.2, glyphs appear broken or missing, suggesting that:

• The Ethiopic-supporting font is no longer being loaded, or
• Font fallback for the Ethiopic script is failing, or
• Text shaping for Ethiopic is broken in this version

Could you please confirm:

• Which font(s) Telegram Desktop currently uses for Ethiopic scripts on Windows?
• Whether there was a recent change in font handling or fallback logic?

If the required font is no longer bundled, it would help to know which font is expected so users can install or configure it manually as a workaround.
