If you see strange characters in the topic list, or unexpected topics comprised of only a few characters, it may have to do with the character encoding of the file on which you base your Explorer project. 

Most likely, your file contains text with mixed character encodings, for example ISO-8859-1 (Latin-1) mixed with Windows-1252.


If this situation arises, make sure your file is encoded using UTF-8, and upload it again.
