Where 1252 fits
Why 1252 is special
1252 extends Latin-1 with curly quotes, dashes and the euro sign in a range other encodings use differently. Text written in 1252 and read as UTF-8 is where ’ appears instead of an apostrophe — the single most common encoding failure visible on the web.

Windows-1252 places curly quotes, dashes and the euro sign in a range other encodings use differently, so text written in it and read as UTF-8 produces the most recognisable garbling on the web. The fix is always to know which encoding a file is in, which is exactly what plain text does not record.
