This does not explain your preference of "Latin-1" over "Latin1".
Both are perfectly valid abbreviations for "Latin Alphabet No. 1".
The spelling without "-" has the advantage of being a valid Python
identifier and a module name.  The IANA registration for "latin1" and
lack of that for "latin-1" most likely indicates that the former is
more commonly found in machine readable metadata.
