I'm in the process of wrapping file in Nu & I asked myself:
What about MIME Types (& Charsets)?

Everything is data. MIME Types describe types of data.

https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types

It would be really nice, if Nushell would understand MIME Types.

As to what the implementation would look like & in what area of Nu it would fit, I am uncertain, which is the reason I open this as a Discussion rather than a clear-cut Issue.

My general idea is the following.

Make Nu support MIME Types explicitly, to add even more compatibility with real world use cases. We already have from json, etc. but supporting MIME Types would add an even wider generic usability surface.

An example use-case I imagine follows.

ls -m | where mime == image/png

Continue the pipe, by processing PNG files explicitly, not only files ending with png, which could be anything...
