Windows-1252
Windows-1252 or CP-1252 (code page 1252) is a single-byte character encoding of the Latin alphabet that was used by default in Microsoft Windows for English and many Romance and Germanic languages including Spanish, Portuguese, French, and German (though missing uppercase ẞ). This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa.

It is the most-used single-byte character encoding in the world. As of December 2023, 1.3% of all web sites declare ISO 8859-1 which is treated as Windows-1252 by all modern browsers (as demanded by the HTML5 standard), plus 0.3% of all websites declared use of Windows-1252, for a total of 1.6% (and only 14 of the top 1000 websites).
Depending on the country or language, in 2023, use (on websites at least) can be much higher than the global average, e.g. (including Windows-1252), for Brazil according to website use, use is at 3.8%, and in Germany at 3.2%. (these are the sums of ISO-8859-1 and CP-1252 declarations).
