Multiple issues:
  * the encoding is not always ASCII
  * what ASCII code is assigned to я
  * dash isn't internationalised
    (this is nonconformant but out of scope),
    and uses the next /byte/; in a UTF-8 locale:
      $ printf %d\\n \'ą
      196
      $ printf %d\\n \'я
      196
    this is in contrast to POSIX (and bash), which says:
      > If the leading character is a single-quote or double-quote,
      > the value shall be the numeric value in the underlying codeset
      > of the character following the single-quote or double-quote.
    (i.e. mbrtowc(&val, argv[n], ...))
