Thank you.
Thank you all, and I think I've found the problem: If you don't use
'Recursive Reference' feature, all will work well.

The above works fine with e.g. FF3.6 amd Konqueror 3.5. Besides, many domain registrars also limit the available characters to those that are part of a national alphabet. National alphabet? Never heard of it -- what Nation? Perhaps not the correct expression, but most non-English languages have their own alphabets, and despite some countries sharing a language, what they allow for domain name registration isn't always the same (ref. Michelle Konzacks earlier posting). For instance, while 'ï' is used in Dutch, English, and French (I believe), it is not used in Danish, so it is not allowed in Danish domain names. Here is the list of characters accepted by the German registrar: http://www.denic.de/de/domains/internationalized-domain-names/idn-liste.html The Swiss registrar: https://www.nic.ch/reg/wcmPage.action?res=/reg/guest/faqs/idn.jspplainlid=de Austrian registrar: http://www.nic.at/fileadmin/www.nic.at/documents/idn/idn_at_tld_de.txt Danish registrar: https://www.dk-hostmaster.dk/selvbetjening/koeb-dk-domaenenavn/tegnsaet-for-domaenenavne/ (quite limited: a-z, 0-9, hyphen, æ, ø, å, ö, ä, ü, é) Are the Greek letters Sigma, Delta, Pi part of this National alphabet? No, only the Greek alphabet which probably is used in Greece and Cyprus only. In addition, many registrars are clueless about IDNS, Char Sets, and what is legal and not. Not in my experience. The various national/European registrars usually have very strict regulations, and any domain registrar offering his or her services to the public had better understand them. -- Per Jessen, Zürich (0.0°C) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Brown Daniel et al: Translation of Unicode characters by various software programs is unpredictable -- this includes email applications. While I can send/receive (square root) through my email program (Eudora) what your email program displays to you can be (as shown) something completely different. The mapping of the code-points (i.e., square-root) to what your program displays (much like a web site) depends upon how your email program works. If your email program has the correct Char Set and will map it to the what was actually received, then the character will be displayed correctly. If not, then things like .com happen. Unfortunately, this mapping problem has not been of great importance for most applications. As it is now, most applications work for English speaking people and that seems good enough, or so many manufactures think. However, as the rest of the world starts using applications (and logging on to the net) it will obviously become more advantageous for manufactures to make their software work correctly for other-than-English languages. Apple is doing that and last year the majority of their income came from overseas (i.e., other than USA). The mapping of other than English characters was the problem addressed by the IDNS WG, where I added my minor contribution circa 2000. Unfortunately, homographic issues were not resolved by the WG. However, a solution was proposed (I entitled as the Fruit-loop solution) which was to color-code (flag) the characters in the address bar of a browser IF the URL contained a mixed Char Set. Unfortunately, that solution was not pursued and instead Browser manufactures choose to show raw PUNYCODE, which was never intended to be seen by the end users. A giant step backwards IMO.

As such, we were allowed to register IDNS domain names on a trial basis. The conditions of the trial were that we could register any IDNS we wanted (at $100 a pop) and if at anytime over the following year our names caused problems, then we would forfeit our names without compensation. In short, a $100 per-name bet! At that time, I registered almost 30 names. Fortunately, all of my names passed and I was permitted to keep them. Unfortunately, all browser manufactures (except Safari) negated some of the work done by the IDNS WG and as a result PUNYCODE is shown instead of the actual characters intended. I continue to hold on to my domain names because I believe that the PUNYCODE problem will be resolved someday and my single character domain names will be valuable. Please realize that single character ASCII characters are estimated to sell for over a million dollars each -- you may want to review this: http://www.cbsnews.com/stories/2005/11/28/tech/main1080245.shtml In any event, this is out of the main stream of PHP. However, it should just be noted that Unicode characters, which started this thread, are very involved and many software manufactures are not implementing solutions correctly. In contrast, the PHP community has provided numerous Multibyte String Functions (mb_) for dealing with Unicode. So, our PHP applications can correctly deal with what Unicode provides that are far exceed simple ASCII.

It was never the intention of the IDNS WG for the end-user to see PUNYCODE, but rather that all IDNS be seen by the end-user as actual Unicode code points (Unicode characters).
