ms-1252

Windows-1252 or CP-1252 (code page 1252) is a single-byte character encoding of the Latin alphabet, used by default in the legacy components of Microsoft Windows for English and many European languages including Spanish, French, and German.
It is the most-used single-byte character encoding in the world (on websites at least). As of July 2022, 0.3% of all websites declared use of Windows-1252, but at the same time 1.2% used ISO 8859-1 (while only 4 of the top 1000 websites), which by HTML5 standards should be considered the same encoding, so that 1.5% of websites effectively use Windows-1252. Pages declared as US-ASCII would also count as this character set. An unknown (but probably large) subset of other pages use only the ASCII portion of UTF-8, or only the codes matching Windows-1252 from their declared character set, and could also be counted.
Depending on the country, use can be much higher than the global average, e.g. for Germany, according to website use (including ISO-8859-1) at 4.6%.
