Create Zip with utf-8 Filenames (Unicode filenames)

See more Zip Examples

Demonstrates how to create a .zip archive that stores the filenames using the utf-8 character encoding. This allows for filenames of any language to be within a single Zip.

Note: utf-8 is the multibyte encoding for Unicode. When a Zip compression product declares that it supports Unicode filenames, what it really means is that it is capable of reading/writing utf-8. WinZip added support for Unicode (utf-8) filenames starting with version 11.2.

Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local zip = chilkat.Zip.new()

local success = zip:new_zip("test.zip")
if not success then
    print(zip.last_error_text)
    return
end

-- To zip using utf-8 filenames, set the OemCodePage = 65001
zip.oem_code_page = 65001

local recurse = true
success = zip:append_files("/temp/NonEnglishFilenames/*", recurse)

success = zip:write_zip_and_close()
if not success then
    print(zip.last_error_text)
    return
end

print("Zip Created!")
