revZipEnumerateItems mistake with diacritical chars

It seem revZipEnumerateItems don't like diacritical chars and it seem necessary to use urlEncode(MyfileName) to keep the diacritical chars.
I testes it with two small zip (LC 5.02)
• Zip 2
Name of files in the zip (not urlEncoded):
"août.png"
"affûter.png"
revZipEnumerateItems return:
Problucirc/affuÃÇter.png
__MACOSX/Problucirc/._affuÃÇter.png
Problucirc/AouÃÇt.png
__MACOSX/Problucirc/._AouÃÇt.png
Name of files on the disk:
"affuÃÇter.png"
"AouÃÇt.png"
• Zip 2
Name of files in the zip (urlEncoded):
"aff%9Eter.png"
"_ao%9Et.png"
revZipEnumerateItems return:
ucircencoded/aff%9Eter.png
__MACOSX/ucircencoded/._aff%9Eter.png
ucircencoded/ao%9Et.png
__MACOSX/ucircencoded/._ao%9Et.png
Name of files on the disk:
"aff%9Eter.png"
"ao%9Et.png"
Is it a bug for you or not ?
Best regards

Hi Jean-Marc,
No, this isn't a bug. The file names in your file are stored as UTF8:
Code: Select all
put uniDecode(uniEncode("AouÃÇt","UTF8"))
-- Août
Kind regards,
Mark

Hi Mark,
The file names in your file are stored as UTF8
Why ?
I expected a same result when I decompress the zip by the finder
Kind regards

Hi Jean-Marc,
Did you try to compress files in the Finder and decompress them with LiveCode? Did you get a result different from if you compress and decompress them with LiveCode only?
Kind regards,
Mark

Yes

Yes. revZipper keep the original names "août" and "affûter".
How can I know if a zip has been compressed with the finder or LiveCode ?
Kind regards

Hi Jean-Marc,
Take the 7th and 8th byte of the zip file and look at the 11th bit of these bytes together (that's the 3rd bit of the 8th byte). If this bit is 0, the file names are probably Latin 1 encoded but may be MacRoman encoded. If the bit is 1, the file names are UTF8 encoded.
(If you look at the ZIP specs, you will probably read 6th and 7th byte, but that's because the specs start counting at 0 rather than 1. You can find the specs at
http://qery.us/3dl and search for "UTF-8").
Kind regards,
Mark
