Summary:
This time, ICU is. It is also very famous UNICODE libraries.
ICU is, UNICODE is a library for handling. Has cross-platform, Linux on the UNICODE system control is being used as well. In addition, BOOST other libraries, such as in dealing with UNICODE, in general are often linked to ICU.

The latest version of ICU, VC + + support for the latest version of the (project file) is done only. Therefore, VC + + If you compile the latest version is the only good solution to build the open.
(% ICU installation directory% \ icu \ source \ allinone \ allinone.sln)

However, the old VC + +, compile (install) If you do, you need a little more effort.

This time, leave the settings described in that environment.

Summary:
Well on Windows, GCC and VC + + compilers are compared.
Personal opinion is any better compiler, you use either, and I feel like the taste of the developer.

This is a dare, on this question, decorated the optimization program is run so that one reference, I have a simple sample program to check how much sooner.

Now that you mentioned is actually my PC (WindowsXP) and described the results of our run. However, that sample is just one example, please advance our understanding.

CxImage demo software that you use the library, in English only of course, tried to create a Japanese version.
This demo is the demo version of the split, I think that well. If a simple image analysis may be able to offer.
However, the demo version, but I have some bugs, you can also download the source code to try and think everything is convenient.
PhotoShop and PaintShopPro like the concept of layers is not, and do analysis of a single image, PaintShopPro it is merely functional.
