Cached text/plain document has wrong encoding
I'm using 64-bit firefox developer edition 49.0a2 on windows 10.
I have a UTF-8 encoded text/plain document up on my server that is served with the proper Content-Type, but is decoded with the wrong encoding (iso-8859-1, I think) when loaded from the cache. I assume this is because the encoding is not stored in the cache, but I am not sure how to look into the problem further.
Is this a bug? If so, where should I file a bug report?
If your default encoding is not utf-8, you should be able to reproduce the issue by visiting the document and then reloading with the developer tools closed. ctrl-F for "- quick fix", underneath it should be the word "ÜberCharge" which will decode incorrectly with a different encoding.

A possible workaround is to add a UTF-8 BOM at the start of the file. Then it also works if you save the file to the hard drive.
Yeah, that would prevent the issue from occurring for this file, but I am wondering if this is a bug or not. Are you saying it isn't?
Firefox default to iso-8859-x encoding, so when the encoding that the server sends isn't available then you get issues. I use some text files in pinned tabs to quickly access notes and answers to question and came across this issue and decided to add the BOM to avoid having to correct the encoding on each page reload. An HTML file can have a meta tag to set the encoding and a text file a byte order mark.
Yes, I am aware of that. Allow me to restate my question:
Firefox does not cache the encoding of plain text files. Is this a bug? If so, where should I report it?
