Showing full arguments in the stack trace

[perlancar]

I'm getting error in a particular cron task. After running cron.php with "do SslSync -vvv" on the command line, the error message is something like:

[ERROR] exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1253 COLLATION       
         'utf8_unicode_ci' is not valid for CHARACTER SET 'latin1'' in                                                  
         /home/foo/public_html/vendor/illuminate/database/Connection.php:333                          
         Stack trace:                                                                                                   
         #0 /home/foo/public_html/vendor/illuminate/database/Connection.php(333): PDO->prepare('select
         `userid`...')                                                                                                  
         #1 /home/foo/public_html/vendor/illuminate/database/Connection.php(706): 
         ...

Is there a way to see the string arguments in full? Tried StackOverflow, the proposed solutions involve changing the source code.
