- The Ver.7 document whose size of height or width is more than 500 mm, or data size exceeds 250 MB remains Ver.7 document even if Unicode is converted into the multi-byte code.
- As the result of conversion from Unicode data to multi-byte code data, any characters that cannot be converted properly are replaced with "?" or "_".
- DocuWorks containers, documents protected with "Password (256bit V8 or later)", and documents protected with "Digital Certificate (256bit V8 or later)" (these are all Ver.8 documents) are skipped without being converted to multi-byte code.
