Series import: fails to insert a URL with Russian symbols

[php-coder]

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [INSERT INTO series_import_requests ( url , status_id , updated_at , requested_at , requested_by ) SELECT ? , st.id , ? , ? , ?

Looks like a regression after ffc0acd commit where the character set of the table to ascii.

Now it fails with another exception:

Caused by: org.springframework.dao.DataIntegrityViolationException: PreparedStatementCallback; SQL [INSERT INTO series_import_requests ( url , status_id , updated_at , requested_at , requested_by ) SELECT ? , st.id , ? , ? , ? FROM series_import_request_statuses st WHERE st.name = ?]; Data truncation: Data too long for column 'url' at row 1; nested exception is com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'url' at row 1

It has happened because after encoding, url became longer (478 chars).
