BTW; you may want to consider using ISO 8859-15 (Latin 9) instead
of ISO 8859-1 (Latin 1); Latin 1 is widely outdated, and Latin 9
contains a few other characters like the € (Euro Sign). If that is
possible for your context you have to map a handful of characters.

Latin-1 maps exactly to Unicode for the first 256 values.  Latin-9 does
not, which would make the translation more difficult.

<https://en.wikipedia.org/wiki/ISO/IEC_8859-15> includes a table showing
the 8 characters that differ betwween Latin-1 and Latin-9.

If at all possible, it would be better to convert to UTF-8.  The
conversion is exact and reversible, and UTF-8 has largely superseded the
various Latin-* character encodings.  I'm curious why the OP needs
ISO8859-1 and can't use UTF-8.
