As reported in proper-testing#318, `proper_types:string()` may generate invalid Unicode strings; the Erlang type language overapproximates the set of lists that represent valid Unicode strings. This `proper_unicode` module is therefore extended with functions that generate valid UTF-8 character lists.

As reported in #318,
proper_types:string()may generate invalid Unicode strings; the Erlang type language overapproximates the set of character lists that represent valid Unicode strings.This PR extends the
proper_unicodemodule with functions that generate valid UTF-8 character lists.Like most
proper_typesgenerators, these functions are auto-imported and thus one can writewithout having to specify the
proper_unicode:module prefix.Closes #318
