According to the Pickaxe, or at least the online version thereof
(my dead-trees vesion is at home), /s means to use the SJIS 
(Shift-Japanese Information Systems or something like that) multibyte
text encoding.   Similarly,  /e means to use EUC, and /u means to use
UTF-8.  So /u is probably a better bet than /s for Yvon.
