The Unicode Transformation Format (UTF) is a character encoding format which is able to encode all of the possible character code points in Unicode . The most prolific is UTF-8, which is a variable-length encoding and uses 8-bit code units, designed for backwards compatibility with ASCII encoding.
Universal Mobile Telecommunications System (UMTS) is a third-generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunications Union IMT-2000 standard set. UMTS uses wideband code division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.
