Symbols are commonly used in all forms of design, because they allow for the conveying of meaning without using words (such as “click here” or directions). Symbols are often more universal and language-independent, making them ideal for designs that need to be understood by everyone.
One of the issues that used to present in digital designs that used lots of symbols is that you’d have to manually import each one. But now, there are symbol fonts that correspond a symbol with each letter in the alphabet.
In this post you’ll find some symbol and pictogram fonts that you can download and use to add symbols in your design:
