Change a Unicode project into a non-Unicode one?

[passerby]

I have built a project with Unicode enabled (when creating the project with the wizard).
However, it turned out that wxTextCtrl doesn't display text with accented characters (displays only non-accented text).
Testing just a wxTextCtrl box in a non-Unicode project shows that it displays accented text fine.

So I now want to disable Unicode in my initial project, but can't find where I can do this.

Could someone help with this, please?

Edit: Never mind, figured it out.
