latin1 to utf8

I am using mysql and have some data in my application in the latin1
charset. I have a necessity to support the utf 8 charset. Now I want to
migrate the data between these two charset.

The normal way I do migration is as follows:

Taking a dump of the data with the currently running mysql
converting the necessary parameters in the mysql settings and starting
the mysql with utf8 support
droping the database.
replacing latin1 to utf 8 in the dump.sql file
loading the data back on to the mysql db.
I am fearing of a data inconsistency in the way I do....

Is the above way fool proof and will not cause any data loss or there
is a easy way to convert things to utf8 support using mysql commands
without using a dump.

Appreciate a quick response.

Thanks ,
Ranjith

I don't know any answers to your questions, but here is something to
read about:
http://dev.mysql.com/doc/refman/5.0/en/charset.html

ALTER TABLE tablename charset='utf8';

Doesn't that work? Keep in mind that it's basically going to do what
you are doing - create a new table (with utf8 charset), copy the data
over, and rename the table.

If you need MySQL (or PostgreSQL) training, we offer a wide range of
both. (http://www.otg-nc.com)

Assume you have two varchar (or Text) columns named L and U which are identical except that the charset for L is latin1 and the charset for U is utf8. All the records in L and U are identical in terms of content, consisting of only 7 bit ASCII characters. Both columns have indexes of the same type (e.g. assume Unique indexes if you want). Here's my question: Will the fact that column U has a utf8 charset make select queries run slower on...

Hi, I'm trying to restore a pg_dump-backed up database from one server to another. The problem is that the db is "mixed encoded" in UTF-8 and LATIN1... (weird but, yes it is ! It was ported once from a hypersonic db... that screwed up something and now I'm fighting with that...). So, trying to restore that db into a UTF-8 encoded new one, gives me errors ("invalid unicode character..."), but importing it
