Not in any ICANN contracted TLD such as .com, nor in most ccTLDs.

They each IDN tables which define what codepoint combinations are
allowed in a label. You can find an incomplete set of the tables here:

A few ccTLDS like .WS allow anything that can be represented as an
A-label, but that's hardly the only reason to avoid .WS.

PS: A few names in .COM and .NET don't follow the script rules because
they were registered before the script rules were created. I've done a
survey of them and found none that were malicious or particularly
misleading.
