Our project requirement is that all texts in the Scada will be in Greek. I want to make a msgbox with a message to the user. I used the following script in attachment script.jpg to get the result in attachment msgbox.jpg.
Is there a way to make it show the text properly?
Regards

Try:
system.gui.messageBox(u"your warning text", u"Your title text")
Hi!
Try putting a ‘u’ in front of the string. That will force unicode encoding.
Example:
u"Ένας Έλληνας string είναι σε Unicode"
Also be sure you’re using a fairly recent version of Ignition. IIRC, 7.5.12 or newer, 7.6.4 or newer and any 7.7 should all draw Greek correctly if you put the u in front of strings in your scripts.
