Difference Between UTF-8 and UTF-16

1) UTF-8 uses one byte at the minimum in encoding the characters while UTF-16 uses minimum two bytes. ... In short, UTF-8 is variable length encoding and takes 1 to 4 bytes, depending upon code point. UTF-16 is also variable length character encoding but either takes 2 or 4 bytes. On the other hand UTF-32 is fixed 4 bytes.

Should I use UTF-8 or UTF-16?

Depends on the language of your data. If your data is mostly in western languages and you want to reduce the amount of storage needed, go with UTF-8 as for those languages it will take about half the storage of UTF-16.

What is the difference between utf8 and UTF-8?

The :utf8 encoding, and variations on it without a hyphen, is Perl's looser encoding. Using UTF-8 , in any case and with either a hyphen or underscore, is the strict, valid encoding and gives a warning for invalid sequences.

Is UTF-16 same as Unicode?

Current Unicode 8.0 specifies 120,737 characters in total, and that's all). The main difference is that an ASCII character can fit to a byte (8 bits), but most Unicode characters cannot. ... UTF-8 uses 1 to 4 units of 8 bits, and UTF-16 uses 1 or 2 units of 16 bits, to cover the entire Unicode of 21 bits max.

Why is UTF-8 used?

Why use UTF-8? An HTML page can only be in one encoding. You cannot encode different parts of a document in different encodings. A Unicode-based encoding such as UTF-8 can support many languages and can accommodate pages and forms in any mixture of those languages.

Why does UTF-16 exist?

UTF-16 allows all of the basic multilingual plane (BMP) to be represented as single code units. Unicode code points beyond U+FFFF are represented by surrogate pairs. ... The advantage of UTF-16 over UTF-8 is that one would give up too much if the same hack were used with UTF-8.

What UTF-8 means?

UTF-8 is a variable-width character encoding used for electronic communication. Defined by the Unicode Standard, the name is derived from Unicode (or Universal Coded Character Set) Transformation Format – 8-bit.

Can UTF-8 handle Chinese characters?

It's not that UTF-8 doesn't cover Chinese characters and UTF-16 does. UTF-16 uses uniformly 16 bits to represent a character; while UTF-8 uses 1, 2, 3, up to a max of 4 bytes, depending on the character, so that an ASCII character is represented still as 1 byte. ... Make sure every part of your setup works in UTF-8.

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 the meaning of UTF-8 in HTML?

Here is a definition of UTF-8: UTF-8 (U from Universal Character Set + Transformation Format—8-bit) is a character encoding capable of encoding all possible characters (called code points) in Unicode. The encoding is variable-length and uses 8-bit code units.

What is Unicode with example?

Unicode is an industry standard for consistent encoding of written text. ... Unicode defines different characters encodings, the most used ones being UTF-8, UTF-16 and UTF-32. UTF-8 is definitely the most popular encoding in the Unicode family, especially on the Web. This document is written in UTF-8, for example.

Why did UTF-8 replace the ascii?

The UTF-8 replaced ASCII because it contained more characters than ASCII that is limited to 128 characters.

What is a Unicode format?

Unicode is a universal character encoding standard that assigns a code to every character and symbol in every language in the world. Since no other encoding standard supports all languages, Unicode is the only encoding standard that ensures that you can retrieve or combine data using any combination of languages.
