Problems with text appearance in a DrawLabel

[Huebschmann]

We have a problem with the appearance of text displayed in a DrawLabel (com.smartgwt.client.widgets.drawing.DrawLabel). Dependent from font height and letter combination, the distance between the letters is not unique.
The image illustrates the behavior on the left side. For contrast, at right side the same text is displayed in a Label (com.smartgwt.client.widgets.Label). Here the distance between the letters is unique.
Is it possible to display the text in a DrawLabel with the same behavoir as in the Label ?
We can not use a Label for our application, since we have the requirement of rotation of the text.

DrawLabels are drawn by the native HTML5 capability, and on some browsers on some computers this can differ from normal HTML in details such as text kerning. Unfortunately web applications do not have control over these details of rendering.
