Subbu commented on TIKA-4370:
-----------------------------

[~tallison]  thanks for the response.

Right, The problem is not specific to text file vs binary. I am trying to 
detect Shift-JIS encoded file types and as the magic bytes are mostly UTF8 
based we get back application/octet-stream without file names.

Do you think it's worthwhile for me to consider something like, trying to 
convert input to Shift-JIS and using for prefix in 
[https://github.com/apache/tika/blob/9a6bda5fadcc4c287926ec3361c6f398d113eab0/tika-core/src/main/java/org/apache/tika/mime/MimeTypes.java#L527?]
 

Or some other way to support Shift-JIS that could be a starting point?
