parse error: Invalid string: control characters from U+0000 through U+001F must be escaped at line 56, column 1

why? it was working before and geth t8n accepts it. (actually all the other t8n's are fine)

@shemnon any insight on why we might have t8n parsing issues in the latest main?

[winsvega]

It might be still this one

#5934

If it appers again I reopen the issue

[shemnon]

There are two issues: (a) the error in #5934 and (b) our encodeing trips up retesteth because of escaped tabs and newlines. This bug will track the latter.
