Yes, it could. If you are using the UTF-8 database w/ European characters,
you are not just expanding the size to 2 but you also carry the DBCS-like
performance hit to parse the data string (one or 2 bytes). Yet, if you use
the sorted index feature in database, the overhead of sorting Unicode level
is there as well.

If you are using SQL Server, choose binary sort on Unicode is the best
performance choice.

Hi, Santosh.

I am forwarding your questions to the Unicode List, as there are many people
there that know much more than me about web programming and databases.

What I can say, is that I don't see how Unicode could have any noticeable
impact on the performance of a web site: after all it is just a "character

The only difference will be in the number of bytes needed for the text part
of the web site: Unicode often (but not always!) requires more bytes that
other encodings.

But this should have really little influence on performance, if you consider
that plain text should be a relatively a small part of the total information
in a typical web site, which also contains pictures, Java applets, CSS,
JavaScript, HTML tags themselves, and so on.
