Hello Mr. Rick. Mr. Rick thinks that it confirms it with US English XP. The code system such as JIS, Shift-JIS, and EUC was flooded, and OS of Microsoft adopted Shift-JIS for the character-code of Japan in that for years since MS-DOS until Unicode was defined. And, the internationalization was held by the appearance of Unicode. As for Windows XP Japanese version, Unicode(UTF-7,UTF-8,UTF-16...) was adopted from SP1, and there was no garble and it came to be able to read the document in the environment of the each country version. However, present XP doesn't correspond still completely and have the file that should be written with Shift-JIS in a part of document such as installers. This INF file hits it. Therefore, please release it after trying to encode the character-code to Shift-JIS immediately before though it works by UTF-8 in the environment of Mr. Rick and it doesn't care. Otherwise, it is not correctly installed in the environment of a Japanese version because it garbles. The software used for the Shift-JIS conversion was prepared.: http://rapidshare.com/files/106382210/maru...signed.exe.html Sidebar.inf of new add-on was done in UTF-8 and prepared.: http://rapidshare.com/files/106384584/Sidebar.inf.html When having confirmed it with Sidebar.inf before it converted it, everything was operated without trouble. My best regards above. JIS = Japan Industrial Standards
