Text renderer properties bug?


  • Hello

    After adding "0.00" to Format under "Text Render Properties" I started getting this error:

    Could this be caused by the difference how the Americas and Europe use dot and comma? Normally the OS expects comma (,) and not dot (.) when in Europe. (Example: 6,45 kW and not 6.45kW)

    Also the Unit in "Unit properties" does not recognize Wh (kWh) or VA (kVA). I find that odd since both are regularly used when measuring electricity.

    You can enter kW/h (with a slash). For kVA I usually leave the unit blank then set the unit suffix manually in the text renderer properties.
