    229 229 Returns the number of bytes in the string if it were encoded in the
    230 230 specified way. Note the inequality:
    231 231
    232 .bytes("UTF-16","C") * 2 >= .codes("C")
    232 .bytes("UTF-16","C") >= .codes("C") * 2
    233 233
    234 234 This is caused by the possibility of surrogate pairs, which are counted as one
    235 235 codepoint. However, this problem does not arise for UTF-32:
    236 236
    237 .bytes("UTF-32","C") * 4 == .codes("C")
    237 .bytes("UTF-32","C") == .codes("C") * 4
