How to enable HoverTool tooltip for Text?

No warnings on the Python side, but the javascript side says:

Bokeh: ‘point’ selection not available for Text

This makes sense, however, is there a way to enable a tooltip for Text?

I use plot.text just to display a special character where I need it on the canvas.

This is currently supported. Hover tool relies on the hit testing machinery being implemented for a given glyph, and it has not yet been implemented for text. It might make a nice starter PR if you are interested and able to make contributions. Otherwise, a workaround would be to display an invisible (alpha=0) glyph coincident (or roughly coincident) with the test, and let that drive the hit testing and hover tool.
