Question

which encodings do windows use when reading filenames from zip archive thru zip folders?

as far as I know
cyrillic is represented as cp866 and
central european – cp437

what about other?

• Portuguese
• Español (Spanish)
• Français (French)
• Polski (Polish)
• Türkçe (Turkish)
• Deutsch (German)
• Italiano (Italian)
• العربية (Arabic)
• Farsi
• ไทย (Thai)
• 中文 (Chinese)
• 日本語 (Japanese)
• 한국어 (Korean)
• Tiếng Việt (Vietnamese)

I think first seven of this are in cp437.
Chinese may be in Big5
But I know nothing about others.

Answer 1

According to Apache Commons Compress Zip package documentation it’s the platforms default encoding.

Windows’ “compressed folder” feature doesn’t recognize any flag or
extra field and creates archives using the platforms default encoding
– and expects archives to be in that encoding when reading them.
