Thank you! +1 Personally... I would rather see us ditch our compression library for a PEAR-distributable library that is being actively developed. Most of the code in our zip library is 10 years old, and was written by a no-longer active developer.

And this is expected, since the original specification of ZIP did NOT specify character set information for the pathnames. More recent ZIP specifications define a Unicode content field, but this isn't perfect either since the decompressor has to support reading this content field. Regardless... this would need to be implemented in the ZIP creation code. But it is an enhancement, not a bug.

in BASIC mode when viewing attachments' names IMP display them correctly but when downloading in a zip, I see "Anaesthesia f??l - f??oldal.doc" inplace of "Anaesthesia fül - f?oldal.doc" it seems, it is UTF-8 encoded but displayed as plain ASCII Please help! http://sevenzip.sourceforge.jp/chm/cmdline/switches/charset.htm
