Convert "UTF-16 LE" to "UTF-8" and vice-versa

[vonBarbarosa]

Many files inside pbit zipped directory (i.e. Connections, DataModelSchema, DiagramLayout, DiagramState, Metadata, Settings, Version, Report/Layout, Report/LinguisticSchema) are json files enconded with UTF-16 LE. This makes it difficult for versioning repos to diff them.

The Power BI desktop software needs those file to be encoded like this to work.

This way, it's a nice feature to convert those files to UTF-8 on pre-commit, and convert them back to UTF-16 LE on post-commit and post-checkout.

Any suggestions on how to make this, even if you don't submit any PR, are welcome :)

What I have already tried:

I could do it with iconv, but I had some problems because I formatted the json files with jq, and when I formatted back, Power BI didn't recognize the pbit file.

Probably using iconv to convert back and forth will solve it, and working with jq will be another step on another enhancement
