Postech 포스텍: Pohang University of Science and Technology 포항공과대학교 has two IDNs, namely,
http://포항공과대학교.한국 and
http://포항공대.한국 The difference between the two is that the first has university in full 대학교, the second uses a common abbreviation for university which is 대.
After some experimentation I discovered that their website is language is language adaptive. If the "preferred language for displaying pages" is set to Korean then the website text is Korean. If the "preferred language for displaying pages" is set to any non Korean language then the website text will be English. Actually, I have only tested with the languages: Korean, English, Russian, Arabic, Chinese, Japanese, Tibetan and Thai. I am assuming that English will be the default for text with every non Korean language setting.
The "preferred language for displaying pages" can be set by the user in the browser preferences. One can have a priority list of preferred languages. This is passed from the browser to the server via the http header. A good server will do something with this info. Most servers ignore it. Here is a accept-language list from my Firefox ko,en;q=0.91,ko-KP;q=0.82,ko-KR;q=0.73,ru;q=0.64,ar;q=0.55,zh;q=0.45,ja;q=0.36,th;q=0.27,bo;q=0.18,en-GB;q=0.09. ko=Korean and is the most preferred and it results in
http://포항공과대학교.한국 displaying Korean text. The accept-language list bo,en;q=0.91,ko;q=0.82,ko-KP;q=0.73,ko-KR;q=0.64,ru;q=0.55,ar;q=0.45,zh;q=0.36,ja;q=0.27,th;q=0.18,en-GB;q=0.09, where bo = Tibetan, will result in
http://포항공과대학교.한국 displaying English text. You can view your browser accept-language list (actually Safari only sends a single language code) that is sent to the server by visiting
