Is UCS-2 UTF-16?

Is UCS-2 UTF-16?

UCS-2 is obsolete and replaced by UTF-16, which is more powerful, and more efficient (potentially fewer bytes for same number of characters). UCS-2 is fixed width, UTF-16 is variable width with a minimum of two bytes and a maximum of four bytes. UCS-2 and UTF-16 have identical code points for most characters.

Where is UTF-32 used?

The main use of UTF-32 is in internal APIs where the data is single code points or glyphs, rather than strings of characters.

What is GSM 7 bit encoding?

GSM-7 is a character encoding standard which packs the most commonly used letters and symbols in many languages into 7 bits each for usage on GSM networks. As SMS messages are transmitted 140 8-bit octets at a time, GSM-7 encoded SMS messages can carry up to 160 characters.

Is UTF 16 same as Unicode?

UTF-16 is an encoding of Unicode in which each character is composed of either one or two 16-bit elements. Unicode was originally designed as a pure 16-bit encoding, aimed at representing all modern scripts.

What is UTF-8 and UTF-32?

Answer. UTF-8 is a variable length encoding scheme that uses different number of bytes to represent different characters whereas UTF-32 is a fixed length encoding scheme that uses exactly 4 bytes to represent all Unicode code points. UTF-8 is the more popular encoding scheme.
