[jira] [Created] (COMPRESS-429) Expose whether ZIP entry name &
comment come from Unicode extra field
Damiano Albani created COMPRESS-429:
---------------------------------------
Summary: Expose whether ZIP entry name & comment come from Unicode extra field
Key: COMPRESS-429
URL: https://issues.apache.org/jira/browse/COMPRESS-429
Project: Commons Compress
Issue Type: Improvement
Reporter: Damiano Albani
Priority: Minor
It is known fact that detecting the encoding of the name/comment of ZIP entries is a messy process. And that the general purpose bit 11 is often unreliable.
Only the so-called Unicode extra field (if present) can be trusted to reliably determine a ZIP entry name & comment, as far as I understand.
But the current API of Commons Compress doesn't (easily) expose in which situation the ZIP archive reader is.
That's why I propose to add a couple of new getter/setter-exposed fields to {{ZipArchiveEntry}}, e.g.:
{noformat}
boolean hasUnicodeName
boolean hasUnicodeComment
{noformat}
This way it can be easily determined if the value returned by {{ZipArchiveEntry::getName}} or {{ZipArchiveEntry::getComment}} can be trusted. Or if it needs some "character encoding sniffing" of sorts.
What do you think?
