csv_util_pkg.csv_to_array fails on multibyte chars

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create some cvs contatining multibyte unicode characters, i try russian
2. call clob_to_csv - it will raise string buffer too small exception in 
cvs_to_array call

Oracle XE 10g, Windows, UTF8 database
What version of the product are you using? On what operating system?

Solution: 
change in cvs_to_array
  L_CURRENT          VARCHAR2(1);
  l_next             varchar2(1);
to
  L_CURRENT          VARCHAR2(1 CHAR);
  l_next             varchar2(1 CHAR);

inserting CHAR keyword cause database allocate enough bytes to store defined 
number of multibyte characters

I've gotten that error as well, with a non-multibyte clob. I fixed it with the 
following kludge, in my case the CSV had lines that were longer than 4000 
characters long (and I didn't care if they were truncated):

function csv_to_array (p_csv_line in varchar2,
                       p_separator in varchar2 := g_default_separator) return t_str_array
as
...
  procedure save_column is
  begin
    ...
    l_returnvalue(l_idx) := SUBSTR(l_current_column,1,4000);
    ...

Vadimon's fix added to the latest version of the package.
