 To find out if your db supports utf-8, run the following in a shell or similar, assuming the database 
 you're using for vikunja is called `vikunja`:
 
-{{< highlight sql >}}

 SELECT default_character_set_name FROM information_schema.SCHEMATA WHERE schema_name = 'vikunja';

 ### 2. Run the pre-conversion script
 
 Running this will create the actual migration script for your particular database structure and save it in a file called `alterTables.sql`:
 
-{{< highlight bash >}}
+```
 mysql -uroot < preAlterTables.sql | egrep '^ALTER' > alterTables.sql
-{{< /highlight >}}
+```
 
 ### 3. Convert the database
 
 At this point converting is just a matter of executing the previously generated sql script:
 
-{{< highlight bash >}}
+```
 mysql -uroot < alterTables.sql
-{{< /highlight >}}
+```
 
 ### 4. Verify it was successfully converted
 
 If everything worked as intended, your db collation should now look like this:
 
-{{< highlight sql >}}
+```sql
 SELECT default_character_set_name FROM information_schema.SCHEMATA WHERE schema_name = 'vikunja';
-{{< /highlight >}}
+```
