Comment 85 for bug 650498

I believe the form Adolfo has suggested is not adequate to the Ubuntu font. There are several designs of the letter ß. There are two common designs of the letter ß in modern fonts. A design that looks similar to an ſ+s ligature and a design that looks similar to a Greek β, that is to say, numbers 2 and 4 in the following picture:

The Ubuntu font uses the ‘ſ+s ligature design’ (number 2) for LATIN SMALL LETTER SHARP S, but Adolfo has used the ‘β design’ (number 4) for LATIN CAPITAL LETTER SHARP S. I think that is no good. Both letters of the casing pair should use the same design. Using two different designs for them is as inadequate as, for example, using a serif design for LATIN SMALL LETTER X but a sans-serif design for LATIN CAPITAL LETTER X. They just don't match.
