Why UTF-16?

[YeapGuy]

Why is clipious using UTF-16 encoding here

clipious/lib/service.dart

Line 507 in c698bb3

headers: {'Content-Type': 'application/json; charset=utf-16'});

and here?

clipious/lib/service.dart

Line 158 in c698bb3

headers: {'Content-Type': 'application/json; charset=utf-16'});

This causes my WAF (ModSecurity OWASP) to block Clipious' requests. I can of course whitelist this, but is there any reason to be using an encoding that's non-standard and not recommended?
