Right now, my new site is running on a "dev" subdomain with no problems. Later on, when I need to publish the final site, I will need to change the domain name to a Hebrew one (translates into punycode - xn--4dbkls9cj.co.il). It seems like the WP system won't work with that. I've tried both to write the domain name in plane Hebrew directly and with this punycode, but nothing works. It broke the system and I have to "recover" the original site address in the database. So, how can I define my site to run on a Hebrew domain, as described?
