what is the difference between utf8_general_ci and utf8_unicode_ci?
149146
In short: utf8_unicode_ci uses the Unicode Collation Algorithm as defined in the Unicode standards, whereas utf8_general_ci is a more simple sort order which results in "less accurate" sorting results. See the mysql manual, Unicode Character Sets section: ... It can make only one-to-one comparisons between characters.

A character set determines what languages can be represented in the database. Oracle recommends Unicode AL32UTF8 as the database character set. Unicode is the universal character set that supports most of the currently spoken languages of the world.

The utf8_bin collation compares strings based purely on their Unicode code point values. ... utf8_general_ci applies Unicode normalization using language-specific rules and compares strings case-insensitively.

UTF stands for UCS Transformation Format, and UCS itself means Universal Character Set. The number 8 or 16 refers to the number of bits used to represent a character. They are either 8(1 to 4 bytes) or 16(2 or 4 bytes). For the documents without encoding information, UTF-8 is set by default.

['CHAR(n) is a fixed-length character type whose length is from 1 to 32,767 bytes.', 'VARCHAR2(n) is varying length character data from 1 to 32,767 bytes.']

Normally we can set languages in QTP --> Tools --> Options -->General Text Recognition --> Available Languages --> Supported Languages. Pl look into this image for better understanding.

Short answer: In UTF-8, a BOM is encoded as the bytes EF BB BF at the beginning of the file. ... The character U+FFFE is permanently unassigned so that its presence can be used to detect the wrong byte order. UTF-8 has the same byte order regardless of platform endianness, so a byte order mark isn't needed.

It ranges from U+0000 to U+007F, contains 128 characters and includes the C0 controls, ASCII punctuation and symbols, ASCII digits, both the uppercase and lowercase of the English alphabet and a control character. The Basic Latin block was included in its present form from version 1.0.

The way to do that (in this case to insert the ⌘ symbol, is this: Type Option+2318 (hold down the Option key, and type in 2318). The command symbol will magically appear. Remember to return the input selector to your default language (U.S. in the picture shown above).

You exceeded the IDE's printing limit. Hence you are getting SIGCONT. For Codechef IDE, it's around 2^16 Characters. You can try printing the output directly in a file locally. But as you are using chrome os, I doubt if you can compile and execute locally.

UTF-8 is like the other UTF encodings a character encoding to encode characters of the Unicode character set UCS. Base64 is an encoding to represent any byte sequence by a sequence of printable characters (i.e. A – Z , a – z , 0 – 9 , + , and / ). There is no System.

UTF-8 is named for how it uses a minimum of 8 bits (or 1 byte) to store the unicode code-points. Remember that it can still use more bits, but does so only if it needs to. This also means UTF-16 is NO longer backwards compatible with ASCII. Remember ASCII only used 1 byte or 8 bits.

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.

A Unicode-based encoding such as UTF-8 can support many languages and can accommodate pages and forms in any mixture of those languages. Its use also eliminates the need for server-side logic to individually determine the character encoding for each page served or each incoming form submission.
