Hello,  
I use Elastic 7.17 with metricbeat and the sql module.  
The DB connection fails with this line in the log:

```auto
error opening connection: testing connection: parse "sqlserver://elk:J6": invalid port ":J6" after host

```

The DB user is 'elk' and its password begins with 'J6#p'

So I guess the character # in the password is forbidden.  
What are the others ?  
Where are the rules ? (I couldn't find in the docs)

Thank you
