I’m experiencing an issue with Romanian subtitles in Moonfin on iOS.

Romanian characters ș and ț are rendered incorrectly (they appear as ş and ţ with cedilla instead of the correct comma-below characters).

On IOS jellyfin app subtitle work ok, same in Moonfin on LGtv

Playback path

Direct Play

Symptoms (check all that apply)

• Black screen / endless spinner
• Audio only (no video)
• Stuttering / frame drops
• A/V sync issues
• Seeking/scrubbing broken
• Subtitles missing or incorrect
• Unexpected forced transcode
• App crashes / exits

Steps to reproduce

1. Open any movie or TV episode with Romanian subtitles (.srt).
2. Play it in Moonfin on iOS.
3. Observe the Romanian characters.
   Romanian diacritics should be rendered correctly:

• ș
• Ș
• ț
• Ț

Example:

Expected:

Cel mai ciudat era că avea arc și săgeți, înțelegi?

Actual:

Cel mai ciudat era că avea arc Şi săgeţi, înţelegi?

Frequency

Always

Thanks for the report, @madalingui.

Before anyone can pick this up it needs a little more from you, so it has been labelled Missing Logs.

A diagnostic log is missing

Playback problems depend heavily on your media, server, and device, so we need the log to see what actually happened.

Diagnostic logging is off by default and is kept in memory only, so it has to be turned on before you reproduce the problem. There's no log file on disk to go looking for.

1. Go to Settings > About > Diagnostics & Logging.
2. Turn on Enable diagnostic logging.
3. Repeat the actions that cause the problem. Don't restart the app afterwards, restarting clears the buffer.
4. Come back to Settings > About > Diagnostics & Logging and press Copy all logs.
5. Paste it into a comment below, inside a code block.

The report has to end up here on the issue. Send report to server uploads it to your own server, not to us, so the filename it shows you means nothing on our end. That button is only worth using if you administer that server and go and fetch the file yourself, from Administration > Logs, using Save log file, and then attach it here.

Full instructions, including what a report contains and what to redact before posting one: Collecting Logs.

Each label comes off automatically once that piece is sorted.
