 There's a trick here. Blame lax web standards and companies that
don't like standards.

 There's no EN DASH in ISO-8859-1. The first 256 characters in Unicode
are the same as ISO-8859-1, but EN DASH number is U+2013.

 The character code in question (which is present in the page), 150,
doesn't exist in ISO-8859-1. See

 http://en.wikipedia.org/wiki/ISO/IEC_8859-1 (the entry for 150 is
blank)

 The character 150 exists in Windows-1252, however, which is a non-
standard clone of ISO-8859-1.

 Who is wrong ?
 - The guy who wrote the web site
 - The browser that does the trick.
 - Everybody for using a non-standard encoding
 - Everybody for using an outdated 8-bit encoding.

 Don't use old 8-bit encodings. Use UTF-8.

But if I don't, if I only want to just copy and paste some web pages text contents into a tkinter Text widget, what should I do to succesfully make every single character go all the way from the widget and out of tkinter into a python string variable? How did my browser knew it should render an EN DASH instead of a circumflexed lowercase u?
