Subject: [PATCH 2/3] fix String#bytesplice usage, which in order to be able to
 cut UTF-8 characters, requires the string to be encoded as binary, otherwise
 it'll raise a range error

most of the strings passed to #read_str come from downstream usage of itself, so there are more chances of reducing string creation by returning binary strings

+* fix: encode the string to binary when using `String#bytesplice` (if the string is UTF-8 and the range would split multibyte characters, bytesplicing raises an error).
