Remember that my MySQL skills are at the beginner level; and this whole
Unicode / utf8 business always gives me a headache.
Any Unicode or utf8 characters with diacritical marks will look funky in
DOS.
Normally what I do is take my data, convert it from uft8 to utf8, and see if
the results match what I originally had. I'm not sure how reliable this
technique is, but it will at least recognize files which have characters
that are not utf8-encoded. This is counting on the fact that PHP doesn't
recognize this as a null conversion.
My particular problem was that I had files that were created in Windows
applications, using CP1252 encoding. I needed to get these into utf8, and
wanted to test my results. I have a PHP script to do this. My translator
seems to work: at least, my results look right after the translation. What
disturbs me is that the translated (utf8) files also seem to be CP1252,
which seems counter-intuitive. I did this awhile ago, so it may be that
CP1252 has alternate encodings that are a superset of utf8 (and I've
forgotten).
How are you looking at the data? Try directing some of it from MySQL into a
text file, and open the text file with Notepad. It will give you a choice of
opening the file as ANSI, Unicode, or utf8. Try opening the file in Unicode:
if it is not Unicode, then the letters with diacritical marks should look
wrong (or be missing).
If MySQL's engine is as blind as PHP, you can do this in SQL. The problem,
as I see it, is that the engine already believes the data is UTF8 so it
might not work.
SELECT COUNT(*) FROM table1 WHERE CONVERT(field1 USING utf8) != field1;

Subject: RE: utf8 importing problem
Jerry,
I checked the imported data ( sql file) and the data are in
utf8 coding.
Is there a way how to check the imported data in a table
itself, to eliminate the problem in the
application?
Thank you for your reply
L.
Most likely the UTF8 is still in the data base, but
whatever program you are
using to view it is not displaying UTF8 properly. MySQL's
command line
program will not, for example, even if you SET NAMES utf8.

Subject: utf8 importing problem
I use MySQL database with utf8 character set and utf8_czech_ci
collation.
It works well on Linux server but when I try to
export the data and import into the same database but running
on XP machine the utf8 is
gone.Instead of a proper coding there are some strange characters.
I used
mysqldump --default-character-set=utf8 mimi /home/Result.sql
to export data to /home/Result.sql file on Linux machine.
Then I downloaded the file to my XP and here I used
mysql --default-character-set=utf8 mimi Result.sql
to import data.
Is it correct?
Any help would be appreciated
L.
