I have checked with the OAuth signing guide at http://www.hueniverse.com/hueniverse/2008/10/beginners-gui-1.html, which even considers the case of non-English parameters that lead to multibyte characters, and their signature matches mine. I think this is a bug in the way Twitter verifies signatures when multibyte characters are present, and I've filed a bug report with them. Guan
