Is UTF-8 a multibyte?
UTF-8 is therefore a multi-byte variable-width encoding. Multi-byte because a single character like Я takes more than one byte to specify it. Variable-width because some characters like H take only 1 byte and some up to 4. Best of all it is backward compatible with ASCII.
What is Unicode multibyte?
Unicode is a 16-bit character encoding, providing enough encodings for all languages. All ASCII characters are included in Unicode as widened characters. Support for a form of multibyte character set (MBCS) called double-byte character set (DBCS) on all platforms. DBCS characters are composed of 1 or 2 bytes.
What is UTF-8 encoding used for?

What is multibyte characters example?
An example of a single-byte code set is the ISO 8859 family of code sets. Examples of multibyte character sets are the IBM-eucJP and the IBM-943 code sets. The single-byte code sets have at most 256 characters and the multibyte code sets have more than 256 (without any theoretical limit).
Why did UTF-8 replace the ASCII?

For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration. Other Unicode characters are represented in UTF-8 by sequences of up to 6 bytes, though most Western European characters require only 2 bytes3.
