On Android Dynamic Font doesn't support use system font?

I am using Unity4.1.2f1, and the documentation says: when import a dynamic font, I can choose not including extra font data, and set Font Names with a list of font names separated by comma. But when I try to do this, Unity complains that "the target platform does not have access to any system fonts. INcluding Font data even though the importer is set not to". It is confused.

So my question is "On Android dose Unity really support to using system font as dynamic font?"

Please Kindly help me, thanks.
