It is really a balance between contractual enforcement and best
practice.

For gTLDs:

- top level - ICANN contractual term with registry operator

- second level  - ICANN contractual term with registry operator

- third and lower level - best practice/education

(note that some TLDs like .name do support third level directly at the
registry, and hence compliance could be managed at that level)


For ccTLDs:

- top level - ICANN contractual term with registry operator

- second level - best practice/education

- third and lower level -  - best practice/education


To some degree application software can also highlight issues - e.g
display a warning when mixed scripts are detected etc.
