I am developing a Java tools to convert StarDict database to SQLite database for use with an Android Dictionary app. But I get the following error:

Any ideas? Thanks a lot.
The problem is on the line that says:
At a guess,
dictNamecontains a-character, which is not a legal part of a bare literal in SQL. Sanitize, or put"double quote"characters around it. They’ll need backslash quoting to be part of a Java string. But sanitizing (e.g., by stripping all non-alphabetic characters) is much better.
