Feature request: Add optional support for ISO-8859-1 characters

[deniskabana]

Taking my source from https://www.freeformatter.com/html-entities.html

I am working with strings, that have HTML entities coming from the ISO-8859-1 table, like á and he.decode() doesn't transform that and there also isn't any option to enable this optionally.

I understand the list of characters will make the source code larger, so it might be an optional submodule for handling these types of characters.

Example string I have:
BEFORE
& Lepiaca penová páska
AFTER
& Lepiaca penová páska
