Please note that newer versions of the ODBC driver are backwards compatible,
and have bug fixes.

I guess you are asking not for SQL_DESC_LENGTH but SQL_DESC_OCTET_LENGTH?
The latter multiplies the column size (in characters) by the maximum possible
number of bytes per character, which is 4 in the Unicode driver, and 6 when
using UTF-8 as client encoding.  (In driver version 9.6.3, the UTF-8 value
was corrected to 4.)
