Question

how is UTF 8 encoding scheme different from UTF 32 encoding schemes​

Answer 1

Answer:

UTF-8 uses a minimum of one byte, while UTF-16 uses a minimum of 2 bytes. ... On the other hand, UTF-32 is a fixed-width encoding scheme and always uses 4 bytes to encode a Unicode code point.

Answer 2

Answer:

UTF-8 is a variable length encoding scheme and it uses different number of bytes to represent different characters. UTF-32 is a fixed length encoding scheme and it uses exactly 4 bytes to represent all Unicode code points.

Explanation:

• UTF (Universal character set Transformation Format - 8 bit) is capable to represent every character in the Unicode character set.  UTF-8 encodes all 1,112,064 characters which are defined in the Unicode character set.

• UTF-8 is compatible with ASCII.

• UTF-8 requires just one byte for ASCII characters. It has a leading 0. The first byte can contain extra information like the total number of bytes etc.. This is encoded by having leading ones followed by a zero in the first byte.

• UTF-8 has been superseded by UTF-16, and UTF-32. UTF-16 uses  2 byte and 4 byte encodings for all the Unicode characters.

• UTF-32 encodes all Unicode characters using exactly 32 bits.
