[WIP] Display non English characters without conversion to unicode code

[MaxShoshin]

Avoid conversion non english characters to unicode codes:

Current result example:

{
      "message": "\u041F\u0430\u043F\u043A\u0430",
}

After this fix:

{
      "message": "Папка",
}

Thanks for opening this PR. Could you also add a test that covers this?

[MaxShoshin]

Many thanks!
I'll do it

I'm merging this because the failing tests are for a different reason, thank you again for your contribution

[MaxShoshin]

The failing tests are related with indirect reference to System.Text.Encoding.Web (System.Text.Json references 5.0.1), but in .Net Core 3.1 (or earlier), ref assemblies contains this version of assembly with version 4.x.x...

So to fix it - it will be nice to add direct dependency to System.Text.Encoding.Web version 5.0.1.

But i don't think it is a good solution. I've tried to somehow workaround it, but no success on it.

@MaxShoshin I pushed your change into the 1.2.2 release. I bumped the version of the System.Text.Json package to 5.0.2 to fix the failing tests. It looks like System.Text.Encoding.Web.5.0.1 had some security issues anyway.
