Hi,

I'm using the Tree component in Ignition Perspective, and I want to show units like `m/s²` and `°C` in the label.

When I type them manually in the Designer, they show correctly.

But when I set the label using a script, they show incorrectly as `m/s²` or `°C`.

How can I display these Unicode characters properly through scripting?

Thanks!

In python, **string constants** with non-ASCII character's need to have the unicode prefix or the characters will be mangled.

This will work: `u"°C"` and this will not: `"°C"`.
