how many bits emoji?
Unicode â For text messages that include any characters outside of the GSM 7-bit character set, UTF-16 Unicode encoding must be used for the entire message. This encoding uses 16 bits (2 bytes) for each character (with some characters, such as many emoticons requiring 32 bits, or 4 bytes, per character). Each and every character in a Unicode format message must be encoded using at least 16 bits, even if the character is part of the GSM 7-bit character set.
