### How to apply upper case after an O' (like O'Hugo)?

There are irish/scottish names like O'Donnel, O'Leary etc, that all should be upper case. But you cannot use upper case in general after an ' because other words would be spelled wrongly then (That'S, Ain'T etc.).

Action type: Replace with regular expression  
Regular expression: **`O'(.{1})`**  
Replace matches with: **`O'$upper($1)`**  
**[x]** case-sensitive comparison
