Ahh, you must have the "binary-as-hex" setting enabled. Check your conf files in /etc/mysql.

You can pass the command line option "--skip-binary-as-hex" to output normal text. Use "mysql --skip-binary-as-hex webwork" (of course add username and such)

Thanks to both Danny and Glenn! 

Yep, that's it "--skip-binary-as-hex" does the trick and it looks like "binary-as-hex" is the default.

Following Glenn advice: re-saving the those sets from HW sets editors solve the original problem. Now students can see their grades by clicking the grade button.
