IPA: /nɒnˈkærɪktər/
KK: /nɑnˈkɛrɪktər/
Something that is not a character, often referring to a unit of text that does not represent a letter, number, or symbol.
In programming, a noncharacter may be used to represent a space or a control function.
Noncharacter → It is formed from "non-" (meaning not) and "character" (from Greek "charaktēr", meaning a distinctive mark or feature). The word "noncharacter" refers to something that does not possess distinctive traits or qualities, essentially meaning not a character.
Think of 'non-' meaning 'not' and 'character' referring to distinctive traits — so noncharacter means lacking distinctive traits.
