Hash function which returns not just lowercase letters and numbers, but also symbols and uppercase letters

All hash algorithms (sha1, md5 etc) seem to return string with lowercase letters and numbers. Are there any algorithms which also return symbols like [ ] \ , ! etc. and uppercase letters?

A typical hash function (like MD5) produces bytes as output. These bytes are usually hex encoded so that they can be represented as text. However, there are other binary-to-text encodings too.

You seem to refer to the hexdecimal-ascii representation ("letters and numbers") of the hash. That's just a different way of saying "number", only with sixteen symbols instead of ten as in decimal or two in case of binary.

You can map the hash - which is just a number like any other - to any representation you want. You may, for example, base85-encode the hash which gives you a ascii-string like ">uD.RTpAKYo'+CT/5+Cei#DII?(E,9)oF*2M7/c~>", depending on the size of the hash.
