Subject: Re: Internal string storage and Encoding::Converter#convpath

For encodings that can be converted directly (like EUC-JP to SJIS), I understand that no UTF-8 internal storage is required. However, what about encodings that do require an intermediate step? Is the choice of UTF-8 as an intermediate representation an implementation detail?

Thanks,
