How? I tried to look for ANY information about localization and input methods, which code pages are used, etc., and couldn't find anything at all. That includes the forum. There's pretty much no technical information.
I would say you are missing the point of what the site is all about. You don't go to the site for indepth technical details for coding purposes. The site is basically to market the product, give people an over view of the product and it supplies links and ways to get to the different specialised areas to do what you are talking about.
As an example, you don't go to
http://www.microsoft.com and expect to get coding or sysadmin tipsdirectly from it, Microsoft provides links to technet.microsoft.com for that purpose. The main purpose of the
http://www.microsoft.com site is to show case and talk about their products as a marketing and sales exercise and as a door way to the rest of the information and that is what the
http://www.amigaos.net is for as well.
