In this web site, most pages are in English or German, and so use the Latin character set. Since on some pages I also use Cyrillic (Russian) letters and Chinese characters as well as extended Latin letters, i.e. for representing the tones in Pinyin, all pages are coded as UTF-8 (Unicode).

You can determine whether your operating system can display all characters used in this web site by checking the following table:

standard Latin characters:
to the right, you should see the letter "a" with two dots, with a rising and with a falling accent:
ä á à
extended Latin:
you should see the letter "u" with a bar above, with a "v"-shaped accent, and with two dots AND a "v"-shaped accent
ū ǔǚ
cyrillic (Russian):
you should see an inverted "R" and an inverted "N" (these are the Russian letters "ya" and "i")
you should see a square box and a big "+". These are the characters "wei2" and "shí"

 If you can't see all of these, your system does either not understand Unicode, or you don't have the appropriate fonts installed. Please make sure that your browser's encoding is set to UTF-8 and check your system's documentation..
