Hi ya all,
Got some feedback from Blogger about the comments issue and it seems that the comments pages language can vary from country to country and the end user, in each country must sort out his personal setting, to be able to view the page in the language he wants. Here's the official answer;
Good troubleshooting so far! The comments page your readers get are
dependent on their Blogger and browser settings. If they are a Blogger user,
Blogger will try to use their account settings for your comment page. If they're
not a Blogger user, then Blogger will try to detect language settings from their
browser. So it's up to your readers to select the correct settings.
Hope this helps,
