...oding that is based on ISO-8859-1 but which puts extra characters into the range 0x80-0x9F. Code page 1252 is often confused with ISO-8859-1, and it's an annoying but now-standard web browser behaviour that if you serve your pages as ISO-8859-1, the browser will treat them as cp1252 instead.

What is the difference between char, nchar, varchar, and nvarchar in SQL Server?
... are exceptions, see below). By using two bytes per character, a very wide range of characters can be stored, so the basic thing to remember here is that nchar and nvarchar tend to be a much better choice when you want internationalization support, which you probably do.
Now for some some finer poi...
Matrix Transpose in Python

This works, though there are more Pythonic ways ...
