Na. The number of allowed unicode codepoints is limited for that reason. The coding of the allowed codepoints could still be more readable. But the length of domain names is limited (30 or 35 bytes AFAIK), so shortness was more important than readability. Even more important for non-latin writing system like CJK, cyrillic, greek, arabic, hebrew, etc.
