This is a short memo about installing iconv on Windows host (specifically: Windows 7 SP1 x64). Iconv is a handy Unix/Linux tool that is used for conversion between different character encodings.
Unfortunately, I’m not always in a position to use my favorite Linux distro at job, so here is a short recipe on how to setup iconv port for Win32.

1. Download libiconv-1.9.1.bin.woe32.zip from Sourgeforge.net
2. Download support library gettext-runtime-0.13.1.bin.woe32.zip from here. Make sure that you download exactly the version 0.13.1 and NOT newer, due to some compatibility issues!
3. Create some directory, such as C:\UNIXUTIL\iconv
4. Unzip the content of \bin from both zip files and save the content together in above directory.

The final content of iconv directory should look like this:

C:\UNIXUTIL\iconv>dir
 Volume in drive C has no label.
 Volume Serial Number is A88E-6A42
