Fix character escaping

[rleojoseph]

Description

• Several characters are not escaped properly. This will encode the string that will be sent to MiniApp (MiniApp Bridge will decode it)
  And we are encoding this only for miniappreceivejsoninfo not to break other things

Links

Add links to github/jira issues, design documents and other relevant resources (e.g. previous discussions, platform/tool documentation etc.)
