Maybe yoffset issue is outdated, but I couldn't find any comment that it is solved, so I hope this helps someone.
I use a function below to calculate yoffset.
It is related with the imported font size as Unisip mentioned before (see page 2 of this thread).
So I changed inspector code to get it from the user, designer in my case, as variable 'TTFSize', and added to vert's y value.
Lowercase y or g is still printed below the bottom line, but other letters are in the box.
private float CalculateYOffset()
{
float yoffset = ((dynamicFontSize / (float)TTFSize) - 1.0f);
int lineHeight = (charSize + mSpacingY);
yoffset += lineHeight * (TTFSize / (float)dynamicFontSize);
yoffset -= lineHeight;
return yoffset;
}
Hope 2.6.0 comes soon!
