redmine:migrate_from_trac doesn't work when multibyte characters are used in trac.
redmine:migrate_from_trac doesn't work when I use multibyte characters in trac.
So I wrote a simple patch for this problem.
I think this patch makes the task so slow.
Why the task doesn't work?
Because Ruby's String#[pos, length] counts bytes (Ruby1.8), but database counts characters (varchar(30)).
Another way, you fix database schema.
issue_categories name varchar(30) -> varchar(255)
But this way cannot solves real problem in the task.
