From tidyverse/haven#788 - the new MR set changes only support ascii characters in the set name in the ragel parser, but SPSS uses the file code page/UTF-8 for these.
This PR updates the parser to allow for non-ASCII characters, and runs text from the MR set through
readstat_convert()to make sure the character encoding comes in correctly.
