Re: [code] [textadept] Encoding and display

I think CP1252 would be a better choice as the default single-byte codepage
in Textadept given that ISO-8859-1 in web pages is actually CP1252[1] and
ISO-8859-1 is the most common single-byte encoding in websites. The most
significant difference is that CP1252 has printable characters in the range
80-9F where the original ISO-8859-1 (and the ISO-8859-1 in Textadept) has
control codes or no characters.
