currently cached data. It allows a number of nice things, like: removing
fallback code from single locale loading, remove memory leak when LC_CTYPE
data loaded again and again, efficient cache use, not only for
setlocale(locale1); setlocale(locale1), but for setlocale(locale1);
setlocale("C"); setlocale(locale1) too (i.e. data file loaded only once).
Satoshi NIIMI-san kindly explained that EUC does not limit the byte length to
any arbitrary number.
We now set the limit to the maximum octet length of the codeset and it is
locale-specific.
