What is the problem?

the json string in notepad++ you can see '?' In the ANSI,
Because of this problem json string can not be validator.
you can see my attached file 'new 1.txt'
thank you Erel

Do you want to save the string encoded as ansi instead of UTF8 (UTF8 is usually better)?

You can use File.WriteString2 with "ISO-8859-1" as the charset.

I want upload JSON String to Web.
But after upload, server return error: JSON validator erro. string not JSON.
You can copy 'new1.txt' testing
