Japanese characters are not preserved in backups [BUG}

[nthubgit]

Describe the bug
When a backup is made of a project with files that have Japanese characters in the filename, Mojibake (https://en.wikipedia.org/wiki/Mojibake) occurs.

For example,

Before backup: 更新履歴.txt
After backup: 譖ｴ譁ｰ螻･豁ｴ.txt

This doesn't happen to the migrated files, only the backup.

To Reproduce
See above

Expected behavior
Filenames should be preserved.

Fixed in 1.0.1 by constructing the FastZip object with a new ZipEntryFactory() { IsUnicodeText = true }; to ensure that entries with Unicode text are saved.
