PrintableASCII 99 | Hex 0x63 | U+0063
ASCII 99 encodes lowercase c. C is the name of the programming language Dennis Ritchie developed at Bell Labs between 1969 and 1973, chosen because it succeeded the language B. In hexadecimal, c represents decimal 12. The letter c has no single consistent sound in English, representing /k/ in "cat," /s/ in "cell," and /tʃ/ in "cello," which makes text-to-speech systems treat it as a context-dependent phoneme.
