About

Have trouble with printing UTF-8 stings or saving file with UTF-8 names on Windows?

lua-native is for you:

native.encode() converts from UTF-8 string to system current encoding on Windows.

On other system (Mac/Linux...) it just return the 1st argument.

local native = require('native')
local mbcs = native.encode(utf8string)
print(mbcs) -- prints correctly in Windows/Mac/Linux... console...

native.decode() converts from system default encoding to UTF-8 on Windows.

On other system (Mac/Linux...) it just return the 1st argument.

local native = require('native')
local lfs = require('lfs')

function attrdir(utf8_path)
	local native_path = native.encode(utf8_path)
	local utf8_filenames = {}
  for file in lfs.dir(native_path) do
      if file ~= "." and file ~= ".." then
          utf8_filenames[#utf8_filenames+1] = native.decode(file)
      end
  end
	return utf8_filenames
end

Build

1. You need Lua for Windows installed. It will set a LUA_DEV environment variable for you.
2. Setup a visual studio dll empty project named nconv, add header path $(LUA_DEV)\include and lib path $(LUA_DEV)\lib to options, and link with lua5.1.lib.
3. Build the nconv.dll, and copy to $(LUA_DEV)\clibs.
4. Run the test.lua for test.

Binary

Yes, build is boring, just get a copy of prebuild binary from the download area.

TODO

1. Add to rock repos?
