Fix todo: ISO-2022-CN is x-cp50227 in .NET

[rstm-sf]

Resolve task #78

Not supported iso-2022-ch? Maybe fix to x-cp50227?

Sorry, but I could not find an example.

I'm confused, I’ll fix it now

so 50229 is unsupported but also iso-2022-ch? But x-cp50227 is supported?

[rstm-sf]

Yes, I somehow wrote with a double meaning.

If you go to get the encoding by identifier 50229, then you will get an exception in .NET Framework:

System.NotSupportedException : The ISO-2022-CN Encoding (Code page 50229) is not supported.

It is possible that it was or was supposed to be ISO-2022-CN-EXT encoding.

x-cp50227 has the identifier 50227 and is ISO-2022-CN encoding according to the doc/win32.

P.S. Now I need to make 2 edits
