I'm sure some monks have seen this, or something similar. After this step:

$_ = encode_json $hashref

and

(DBI query) insert into table ( $id, '$_' );

I get

Invalid JSON text: "Invalid encoding in string." at postition 3464 ..

I then did

split //

and that position was the first instance of a \n. It looked like: 

3463 '.'
3464 '\\'
3465 'n'
.
.

so evidently it split \n into 2 chars, \ and n. I'm not sure how to direct the utf conversion to treat \(letter) as a character but I think that's where the JSON string goes south?

I chatGPT'ed issue and most suggestions were to replace all '\' with '\\' , so I tried some replacements like: s.([^\\])\\([^\\]).$1\\\\$2.g which had no joy: same error, same position. I'm wondering would like a cast $_ as json or json_object($_) or some other trick like that help?

AS always kind advice is greatly appreciated, and blessed Friday to all
