Re:It's not unicode - DNS uses punycode (Score 1)

Not true. Chrome displays punycode on a risk based score, and the rules get stricter every release.

Older versions displayed slashdot.org as IDN, newer version only punycode. (I wasn't able to get the U+013C LATIN SMALL LETTER L WITH CEDILLA character through the comment system)

And .org domains have more strict registry rules for example then .com, but there are risky domains even in .org namespace.
You can play on dom.****.com with some tlds and allowed scripts.
