Reproduction steps

1.Describe the bug :

When parsing and displaying articles https://www.developpez.com/rss.php—French special characters (e.g., é, è, ç, à, etc.) are not rendered correctly. Instead, they appear as encoding artifacts like:

Perplexity a lanc� son nouvel abonnement Max, factur� 200 dollars par mois, et d�sormais disponible sur iOS et sur le Web...

This issue negatively affects readability and the user experience for French content.

2.To Reproduce :

Steps to reproduce the issue:

1. Add the feed: https://www.developpez.com/rss.php

2. Sync and open a few articles.

3. Observe that French characters (accents and special letters) appear as corrupted or misencoded symbols (e.g., �).

3.Expected behavior :

French characters should be displayed correctly as UTF-8 or as defined by the feed encoding, for example:

Perplexity a lancé son nouvel abonnement Max, facturé 200 dollars par mois, et désormais disponible sur iOS et sur le Web...

4. Possible cause :

The issue may be due to incorrect or missing handling of character encoding (e.g., assuming UTF-8 without checking the feed's declared encoding). The feed may declare ISO-8859-1 or Windows-1252, which needs to be properly respected when parsing content.
