Latest ODBC driver returns NUL characters in strings with accents (!)

When using MariaDB ODBC connector 3.2.3, strings values are returned with apparently random NUL characters (i.e. '\0').

This issue occurs when string contains accents (french accents : éèàç etc...). There is no problem with older drivers :

• MariaDB ODBC 3.1.19 Driver works fine
• MySQL ODBC 5.1.8 Driver works fine

I attached a sample JSCRIPT to reproduce the bug : run it with CSCRIPT.EXE on a Windows host:

SET MYSQL_PASSWORD=[ROOT_PASSWORD]

CSCRIPT.EXE mariadb_nul_char_bug.js >mariadb_nul_char_bug.log

You need to redirect the script output to a log file in order to see the string difference (NUL characters are not displayed in a Windows terminal).

The test script usually appends NUL characters at the end of string, but in our real application we got NUL characters randomly within strings (not always trailing NUL characters).
