Horizon Attach interface exception, if subnet contains letters with ACUTE

[Peter]

Hy!

We run into a small "problem". (Using Rocky)

A subnet in a project was named with a letter "é" and the horizon dropped an exception, when we tried to attach a new interface to the instance.

When spin up a new instance, and add it to this network, it's just works fine.

After the subnet was renamed, the Attach interface started working again.

Not a big deal, but maybe someone can reproduce, and it can be fixed.

Thanks,

Peter
