…pping json_escape() was silently deleting control characters (U+0000-U+001F) that were not individually handled (\n, \t, \r, \b, \f). Per RFC 8259, these must be encoded as \uXXXX sequences to preserve data integrity. Replace the tr -d strip with a char-by-char loop that emits proper \uXXXX escapes for any remaining control characters.
