Should I use different minimum font size depending on locale?

We all know that if the font size is too small, people wont be able to read it anymore.

Small font sizes are still used. _{Sometimes even in questions and answers on this very site.}

So if for whatever reason I decide to use small font that is barely readable, is it sensible to use the same font size for all locales, or is it expected that I use a larger font size for languages with more complex symbols like 漢字 ?
