I can't seem to find out how to to change the font size in Matlab Help window. It uses by dfault <meta charset="utf-8"> which is annoyingly small.

Try control-shift-plus to increase the size, and control-minus to reduce
the size.

Within your Matlab configuration folder (./matlab/Rxxxx/ under Unix), go to HtmlPanel/.JxBrowser/xulrunner-version--unknown-profile. Here, create a file user.js which contains the line
user_pref("layout.css.dpi", 192);
After that, restart Matlab.

This tells the help browser which is actually a xulrunner application (i.e. based on Mozilla's webbrower technology) to assume a higher monitor resolution and scale the display accordingly. It appears that the standard value is 96, and that changes take only effect in multiples of this number, i.e. 96-191 doesn't change anything, 192-287 leads to a factor two, beyond that three, etc.

I tested this with Matlab R2013a, but I suspect that the same holds for some earlier versions of Matlab.

Btw. @Noriaki, the meta tag you quote has nothing to do with the font size. It just sets the character encoding to UTF-8, which is the way it should be.
