Hi David,
Thank you for the detailed description. That certainly makes things easier to
argue now ;-).
O.K Where to start ?
First, as you know in version 4.0 you can basically set the character sets
only for server and client side (not for DB, table, columns, connection and
result sets).
You could set this from an application like Phpmyadmin I believe, BUT (note
its a big but) if you are on a rental server, than I doubt that this will
work, as you will also change other users character set.
So I guess for now you will have to stay right were you are.
- Using MySQL 4.1
Now lets assume 4.1 becomes stable today or tomorrow (just assuming, I have no
info on this ;-)
In this case you would set the character set for the DB, table,columns etc.
f.e from Phpmyadmin. You would input the query into the editor and ask
Phpmyadmin to execute it.
I have not tried it, but that should work (if you have those privileges).
- Separating the characters for several cgi scripts
I am unable to help here really. I work mostly with a single cgi.
I can imagine that (assuming the cgi supports asian characters) it is just a
matter of passing the right fields to the right cgi script.
I would not suggest mixed fields in a table. Its probably wiser to separate
columns for asian texts and non-asian texts.
- About the search function with asian characters
This is a very hot issue. It wasnt discussed often yet here on the mailing
list. As described on page 21 in my presentation, Regexp() does NOT yet work
with asian characters. Please use "LIKE" for the moment. I am not even sure
if "MATCH ... AGAINST" does work yet.
I believe the manual mentioned somewhere which commands are supposed to work
with asian characters.
- To sum it all up
I hope that this answers the most important ones of your questions. With the
cgi I am a bit unable to help really. If the cgi is known to work with
Japanese characters then it should really just be a matter of separating the
form fields for each cgi script.
However using 4.0.xx your main issue will be that you need to change the
character set on a rental server sharing the same MySQL server with different
users.
