Why do some websites restrict the use of symbols (like %) in passwords?
Usually over-cautious programmers. Behind the scenes it doesn't matter whether you use 'D' or '#', both are pretty much the same for a computer. What *can* but *shouldn't* be tricky are "special" characters.
The Short Answer
Usually over-cautious programmers. Behind the scenes it doesn't matter whether you use 'D' or '#', both are pretty much the same for a computer. What *can* but *shouldn't* be tricky are "special" characters. 'D' and '#' are both parts of the ASCII character set, which is pretty much universal. However, characters like 'ä', 'ß' or 'Û' are *not* universal, there several ways to represent them. This could lead to problems if, say, your Android phone encodes 'ä' as "1234" but your Windows laptop encodes it as "9779". You typed the same letters, but they look different for the computer. [This is of course a bit simplified and some fellow programmer will probably rant about my inaccuracy]
