Describe your issue

Working on a legacy project I had problem getting utility classes generated from some files but not others, even when located next to each other. It turned out after a lot of hair pulling that the problematic files where encoded in UTF-16 with BOM. Converting all files to UTF-8 fixed the problem.

Sugestion: At minimum show an error message when a file can't be processed.

Hello,
I ran into a similar issue where Tailwind CSS wasn't generating utility classes from some files, even though they were next to each other. After some troubleshooting, I discovered that the problematic files were encoded in UTF-16 with BOM. Converting them to UTF-8 fixed the issue. It would be really helpful if Tailwind displayed an error message when it can't process a file due to encoding problems.
