Yaniv Kunda commented on IO-341:
--------------------------------
You might know the charset in advance, but if you're not using BOMInputStream
or the likes (i.e. you have a Reader or simply a String passed to you) you
can't know if a BOM was present unless you check the first char and compare it
to '\uFEFF':
{code:java}
public String stripBom(@Nonnull String s) {
return s.isEmpty() || s.charAt(0) != ByteOrderMark.BOM_CHAR ? s :
s.substring(1);
}
{code}
> A constant for holding the BOM character (U+FEFF)
