If I may chime in, I agree on the need to distinguish letters like these visually. It doesn't have to be in one language; any occasion on which those two characters appear on the same page will do. There is no need to have two different letters look identical. However, I don't believe in creating another codepoint. It's up to the font designers to make sure these characters are sufficiently different to avoid confusion. On the other hand, it has been done! There are occasions on which new codepoints were created for characters that were basically glyph variants. The greek letter koppa springs to mind: there are two glyph variants for this letter, and when it turned out font designers weren't sure how it should look, new codepoints were introduced for the "archaic" koppa, in order to show both variants and avoid confusion.
