Show string as UTF-8

[FranklinYu]

Currently non-ascii text is not supported. For example if we have a JSON like

{"®":true}

It would shows

{
  "®": true
}

reason: the registered trade mark sign is encoded in UTF-8 as C2 AE; when Burp see that, it breaks it into two characters C2 and AE. C2 becomes U+00C2 latin capital letter A with circumflex; AE becomes U+00AE registered trade mark sign.

I don’t know the solution, because ITextEditor is supposed to work like this (unless PortSwigger realize this and create ITextEditor.setText(String)). A solution is to migrate away from the default text editor; I understand that this is expensive.

Note that JSON should always be UTF-8. From RFC 8259, section “Character Encoding”:

JSON text exchanged between systems that are not part of a closed
ecosystem MUST be encoded using UTF-8 [RFC3629].
