bq. 3. Unlike getEncodedLength(byte[],int,int),
getDecodedLength(char[],int,int) doesn't protect against overflow in the int
multiplication by casting to long.
#3 concerns me somewhat, this is an existing problem in trunk (i guess only for
enormous terms, though). Should we consider backporting a fix?
{quote}
The current form of this calculation will correctly handle original binary
content of lengths up to 136MB. IMHO the likelihood of encoding terms this
enormous with IndexableBinaryStringTools is so miniscule that it's not worth
the effort to backport.

> We can remove the overhead of ByteBuffer and CharBuffer wrapping in
> CollationKeyFilter and ICUCollationKeyFilter.
> this patch moves the logic in IndexableBinaryStringTools into char[],int,int
> and byte[],int,int based methods, with the previous Byte/CharBuffer methods
> delegating to these.
> Previously, the Byte/CharBuffer methods required a backing array anyway.
