Cyrillic (Russian) text is corrupted in RSS feed from 4pda.to (shows “�” / black diamonds with ?) #124
Description
When subscribing to a 4pda.to forum RSS feed, FeedMe renders Russian (Cyrillic) text incorrectly. Instead of readable Cyrillic letters, the article content (and sometimes parts of the title/body) becomes a sequence of replacement characters like � or “black diamonds with question marks” (see screenshots). Latin text (e.g., usernames) can still appear, but the Russian text is unreadable.
Example feed URL (4pda RSS):
To Reproduce
Open FeedMe
Add a new RSS feed subscription
Paste the URL above and subscribe
Open any item from that feed (open in reader / full article view)
Observe the text rendering
Expected behavior
Russian text (Cyrillic) should display correctly in the article content (and titles), as readable Russian sentences.
Actual behavior
Russian text is replaced by � and/or black diamond characters with question marks, making the article content unreadable.

Additional context
This looks like a character encoding handling issue (mojibake) — e.g., the feed might be served/declared in a non-UTF-8 encoding (common for some RU sites), but the app may be decoding it as UTF-8 (or ignoring the charset from HTTP headers / XML declaration).
Possible fix directions: respect XML encoding="..." declaration and/or HTTP Content-Type charset; add robust charset detection fallback; optionally allow forcing charset per-feed.
