Wrong sql length measurement in Upgrade Script

During In-Portal upgrade process file "<module-name>/install/upgrades.sql" is processed to match database queries (sql) to one or another In-Portal version. Then sqls from versions, that needs to be executed are executed.

Usually all data in that file is in English, however if someone will place Unicode symbol in there (e.g. character in Russian), then whole sql-version-match stuff will fail.
