+# Lua-iconv
+
+Perform character set conversions in Lua
+
+(c) 2005-11 Alexandre Erwin Ittner <[email protected]>
+
+
+## Introduction
+
+Lua-iconv provides POSIX 'iconv' bindings for the Lua Programming Language.
+The iconv library converts a sequence of characters from one codeset into a sequence of corresponding characters in another codeset.
+The codesets are those specified in the `iconv.new()` call that returned the conversion descriptor, `cd`.
+
+Lua-iconv 7 *requires* Lua 5.1 or Lua 5.2. For Lua 5.0, use the first release (lua-iconv-r1).
+
+Details on iconv may be obtained in the [Open Group's interface definition](http://www.opengroup.org/onlinepubs/007908799/xsh/iconv.h.html).
+
+
+## Download and installation
+
+Lua-iconv can be obtained from [its GitHub project page](https://github.com/lunarmodules/lua-iconv), from a LuaRocks server, or from some Linux distributions which already provide it (eg. Debian).
+
+Unless you downloaded a compiled package, you must build the library for your system.
+If you have LuaRocks installed, all the process is automatic; just fire up your favourite shell and type, as root:
+
+```console
+luarocks install lua-iconv
+```
+
+and the package will be downloaded from a rock server, installed and configured.
+Otherwise, you must compile and install the package.
+In a system with pkg-config (as many Linux distributions and Unix flavors) open a shell, untar the distribution package and, within the program directory, type:
+
+```console
+make install
+```
+
+as root.
+The library will be compiled and installed on the in the correct path (which is defined in lua5.x.pc).
+Compiling on systems without pkg-config requires manual changes in the Makefile (this includes Windows).
+
+
+## Loading and initialization
+
+Lua-iconv is a shared library that must be loaded in the Lua interpreter before use.
+You can simply do a
+
+```lua
+local iconv = require("iconv")
+```
+
+call to load up the library (that, of course, must be installed in a directory from `package.cpath`).
+
+
+## API documentation
+
+```lua
+cd = iconv.new(to, from)
+cd = iconv.open(to, from)
+```
+
+Opens a new conversion descriptor, from the 'from' charset to the 'to' charset.
+Concatenating "//TRANSLIT" to the first argument will enable character transliteration and concatenating "//IGNORE" to the first argument will cause iconv to ignore any invalid characters found in the input string.
+
+This function returns a new converter or nil on error.
+
+
+```lua
+nstr, err = cd:iconv(str)
+```
+
+Converts the 'str' string to the desired charset.
+This method always returns two arguments: the converted string and an error code, which may have any of the following values:
+
+* `nil`
+
+    No error. Conversion was successful.
+
+* `iconv.ERROR_NO_MEMORY`
+
+    Failed to allocate enough memory in the conversion process.
+
+* `iconv.ERROR_INVALID`
+
+    An invalid character was found in the input sequence.
+
+* `iconv.ERROR_INCOMPLETE`
+
+    An incomplete character was found in the input sequence.
+
+* `iconv.ERROR_FINALIZED`
+
+    Trying to use an already-finalized converter. This usually means
+    that the user was tweaking the garbage collector private methods.
+
+* `iconv.ERROR_UNKNOWN`
+
+    There was an unknown error.
