Describe the bug

When playlists are viewed in pipepipe, sometimes the playlist title displayed is translated into the language Zulu. No translation should be taking place (from the correct language that is seen when accessing YouTube outside of pipepipe), especially not to a random language that is not the device setting or the language or location setting in pipepipe.

Pipepipe 5.1.1
Settings>content>app language is set to English

Settings>content>default content country is set to United States

"Wipe cached metadata" in pipepipe doesn't resolve the problem

Clearing pipepipe's app cache in Android OS doesn't resolve the problem

Version

Frequency

Always (100% of the time)

Device

Hello!

This is actually an intentional workaround (often referred to as the "Zulu trick") rather than a bug.

You can find the full context and discussion about this implementation here

Short summary:
Without requesting YouTube data in Zulu (zu), YouTube automatically translates most playlist and video titles into English, losing the original language. Using the Zulu language parameter prevents this auto-translation, preserving the original titles.

The only drawback is that YouTube-generated system terms (like "Mix" becoming "Imiksi" or "Favorites" becoming "izintandokazi") are displayed in Zulu. We chose to accept this minor trade-off because it keeps the original titles intact for the vast majority of videos and user playlists. We might write some code in the future to manually translate these specific Zulu system terms back, but for now, this behavior is expected.

Thank you for bringing this up, but this is currently the intended behavior to avoid YouTube's aggressive auto-translation!
