Haven't tried it myself, but maybe you can use the character map (accessible from start/programs/tools or type charmap in the run dialogue) when you follow the tutorial and reach the step where you insert your new name of the start button. If you don't find the characters you want in there, you can install additional language files from controlpanel/region and language settings/languages.
Thanks guys/gals , I already knew how to change the start button text in English , but I needed to know how to change the language.Charmap didnt work, so I finally did it this way - When I came to the part in the tutorial for entering my own text, I installed a new language, typed the text i needed in wordpad, copied the text from Worpad into Resource Hacker and I was done.
I was confused because the line above the start string said
LANGUAGE LANG_ENGLISH, SUBLANG_ENGLISH_US
and I thought I needed to change it, but it worked anyway
