I had the same problem. In Greek for proper conversion to UPPER() you must suppress accent. Changing collation caused issues in other applications. Putting some REPLACE() functions I had more control on the behavior maintaining collation. Below is my ToUpperCaseGR function.

    SET ANSI_NULLS ON
    GO
    SET QUOTED_IDENTIFIER ON
    GO

    create FUNCTION ToUpperCaseGR
    (
     @word nvarchar(max)
    )
    RETURNS nvarchar(max)
    AS
    BEGIN
        -- Declare the return variable here
        declare @res nvarchar(max)
        set @res = UPPER(@word)
        set @res = replace(@res,'Ά','Α')
        set @res = replace(@res,'Έ','Ε')
        set @res = replace(@res,'Ί','Ι')
        set @res = replace(@res,'Ή','Η')
        set @res = replace(@res,'Ό','Ο')
        set @res = replace(@res,'Ύ','Υ')
        set @res = replace(@res,'Ώ','Ω')


        -- Return the result of the function
        RETURN @res

    END
    GO
