| Subject: | unicode table names not decoded in table_info_all call |
Hi,
Attached a script I wrote for DBI and testing unicode in various DBDs.
It shows that when you create a unicode table name and call
table_info_all you cannot find the table by name comparison and yet it
does exist. If the names returned by table_info_all are decoded as UTF-8
you can find the table. So that suggests DBD::SQLite is not decoding
table names. The same probably applies to unicode column names but
although there is a test to check you can use them and find them there
is no additional code to test if they are decoded as UTF-8 you can find
them.
BTW, some tests DBD::SQLite fails no one really expects it to pass like
unicode parameter name markers so please ignore that test - the script
was written for discovery not to demonstrate any particular bugs.
Output when run on Windows (hence the unicode data out is displayed
wrong so ignore that) is:

I tried it with 1.33 too - same result.
