Not visible and searchable Polish characters

Question

I have a question to you.

I have table where I'm saving names of groups and I can save name with polish characters but this saving like this:

id	name
123	Zarny

When my name is Żarny. And when I do select something like this

SELECT * 
  FROM this_table 
 WHERE name = 'Zarny'

or

SELECT * 
  FROM this_table 
 WHERE name = 'Żarny'

it returns me totally nothing.

Do you have any idea what can I do?

Answer 1

I find the response for my question. I need to set in regedit polish language. In Computer\HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE Im set the POLISH_POLAND.EE8MSWIN1250.
