I tried to replicate your requirement.
Make changes to your code accordingly.

a!localVariables(
  local!specialCharacterIds: { 9, 10, 13, 160, 8203 },
  /* Tab, LF, CR, NBSP, Zero-width space */
  local!sampleText: "John" & char(9) & "Wick" & char(10) & "Test" & char(13) & "Data" & char(160) & "End",
  /* Convert IDs to actual characters */
  local!specialCharacters: a!forEach(
    local!specialCharacterIds,
    char(fv!item)
  ),
  {
    a!textField(
      label: "Comment",
      value: reduce(
        fn!substitute,
        local!sampleText,
        local!specialCharacters,
        " "
      ),
      readOnly: true
    )
  }
)

Let me know if this works for you.
