Bottom of custom font cut off in Opera and webkit

Question

I'm using a custom font in a page I'm developing, Droid Sans, and at certain font sizes, the bottom is cut off, but only in Opera and webkit browsers.

It's easy to reproduce on Google's own webfonts page looking for Droid Sans and showing the whole alphabet at 18px: http://www.google.com/webfonts

It's especially clear for the lower case g.

Is there some css trick / hack I can use to increase the line height / show the whole character or am I really limited to only certain sizes of the font?

line-height and padding for example don't change anything and 20px font-size works fine and at the moment I am using Windows 7.

Edit: By the way, I am aware of a similar question here but as the accepted answer is changing the font size and the rest of the answers do not apply, it is of not much use to me.

Edit 2: An example that at least for now shows the problem (left hand column, under the slideshow, Il Cerca Viaggi).

Edit 3: The problem seems to be limited to Windows although I'm not sure which versions.

Edit 4: I have added a screenshot from Google Webfonts to show that the problem is not specific to the site I'm developing.

Answer 1

Although it is not the solution I am looking for, I have found a possible solution that might work for others:

In my original style-sheet I have specified the font as follows:

@font-face {
    font-family: 'DroidSans';
    src: url('droid-sans/DroidSans-webfont.eot');
    src: local('☺'),
         url('droid-sans/DroidSans-webfont.eot?#iefix') format('embedded-opentype'),
         url('droid-sans/DroidSans-webfont.woff') format('woff'),
         url('droid-sans/DroidSans-webfont.ttf') format('truetype'),
         url('droid-sans/DroidSans-webfont.svg#DroidSans') format('svg');
    font-weight: normal;
    font-style: normal;
}

This is causing webkit browsers to use the woff file / format.

Changing the order of the font specifications and removing the hash-tag after the svg specification (why is that there anyway?), causes webkit browsers to use the svg file / format:

@font-face {
    font-family: 'DroidSans';
    src: url('droid-sans/DroidSans-webfont.eot');
    src: local('☺'),
         url('droid-sans/DroidSans-webfont.eot?#iefix') format('embedded-opentype'),
         url('droid-sans/DroidSans-webfont.svg') format('svg'),
         url('droid-sans/DroidSans-webfont.woff') format('woff'),
         url('droid-sans/DroidSans-webfont.ttf') format('truetype');
    font-weight: normal;
    font-style: normal;
}

This solves the problem, all characters are displayed correctly.

However, at least in Windows 7 64bit, the svg font is not as sharp as the woff font, it's kind of blurry so I will not be using this solution and am hoping for a better one.
