I'm trying to write some arbitrary text to a custom control.  
My code works, but when I try to draw characters such as ü, it displays an empty square where the character would be.  
I need this to work as I intend to support localizations.  
I have checked already, and Tahoma has the required characters. My code is below:

```
string _Label = "Zurück";
Font labelFont = new Font("Tahoma", 9, FontStyle.Bold);
SizeF labelSize = e.Graphics.MeasureString(_Label, labelFont);
this.Width = (int)(labelSize.Width + this.Padding.Horizontal);
e.Graphics.DrawString(_Label, labelFont, Brushes.White, new PointF(this.Padding.Left, this.Padding.Top));

```

Anyone know how to fix this?
