similar member names = profile page error

Two members have similar names: Jupanu and Jupanu'

When I click on 2nd one profile... it goes to first one!
How can I solve this without changing the 2nd username?

See item #18 from the troubleshooting.txt that is included with vBSEO:

18) Links to member profiles with "unusual" characters don't work properly.
You have two options for solving this problem:
- include the [user id] for your user profiles (or)
- enable the following option via your config_vbseo.php (change setting to 1): define('VBSEO_REWRITE_MEMBER_MORECHARS', 0);

can you please explain a bit the first option?
