The third arg to ConvertANSIToUnicode() is the size of the output buffer
in bytes. In this case you should use sizeof(unicode).
This kind of code is the wrong pattern for VGUI2. It will perform really
badly (because of the expensive operations you are running every time
you paint) and makes your layout really fragile. A better model is to
use a label to contain the text you want to draw and use an event to
update text. The position, size and font the label uses should be
contained in a .res file that is loaded by the base frame that owns the
label ( it looks like CBBHudTaskList should be a frame in your case).
If you cannot implement an event driven method then at least use the
::OnTick() method and only change the label text if the state changes.
You can use the ::SetText() label call to set the string to render, and
you don't need to do the unicode translation manually then.
