ASCII Special characters or ASCII punctuations and symbols[1] have been given pronunciations similar to letters and numbers in a radio alphabet specific to some English speaking regions. The most common pronunciations originated with users of Unix systems, which might differ from names defines in several standards.

The different existing names might be related to the different names defines by numerous standards and system sellers, and also by usage.

Each of the ASCII printable characters has multiple names – some formal, some concise, some silly (Intercal is responsible for some of this).[clarification needed][2]
