Description:
Hi there

I user mysql 5.5.5 and myODBC 5.1.6. I programm in ASP.

I have a text column that have null values by default. If I do a

response.write on a column I get some wierd non latin characters out ;-(

This should be read: Močnik s klobaso Of course comparing now like if column<>"" doesn't work as it writes a type error of course.

How to repeat:
Make a text column in database. Default should be null. Make some cells null and some have text includin our characters: čšđćžČŠĐĆŽ.

Try to read the column using myODBC / ASP Vbscript.

Hi Jerry and thanks for your report.

"Močnik s klobaso" hehehe
Now, seriously, can you do the following:
  o Try the same queries against same server but from some client like WB or odbctexx. Report the results back.
  o Do attach complete test case so I can load it in my IIS.
  o Do check charsets used on server.

I think this might be some charset misconfiguration between MySQL server and IIS.
