Folks,

  Misha suggested I send my questions to the list...

> I was reviewing RCSU paper from the UIC-9 proceedings.
>(I did not attend UIC-10 and do not have those proceedings).
>I was wondering if anyone has any stats on UTF-8 for comparison
>purposes? How does LZW and RCSU do compared to UTF-8 in
>terms of speed?
>
> Does anyone have any data on the size of UTF-8 vs Unicode? I realize
>that UTF-8 will be 50% in size for characters in the 7-bit ASCII range
>and that Asian scripts with pure DBCS characters will be 150% in
>size for UTF-8. It appears RCSU paper has an idea of typical data,
>so how does that typical data measure up in size with UTF-8?
>I assume that RCSU authors have some idea of "typical data" and thus
>why they were able to conclude that UTF-8 was not good enough for
>their purposes.
>
> Thanks in advance.
>Randy
