Differences from other Cyrillic alphabets[ edit ] Allowed italic variants of some letters in different languages Serbian Cyrillic does not use several letters encountered in other Slavic Cyrillic alphabets. The regular upright shapes are generally standardized among languages and there are no officially recognized variations.
Japanese bit Shifted Japanese Industrial Standard JA SJIS Subsets and Supersets When discussing character set conversion or character set compatibility between databases, Oracle documentation sometimes uses the terms superset, subset, binary superset, or binary subset to describe relationship between two character sets.
The terms subset and superset, without the adjective "binary", pertain to character repertoires of two Oracle character sets, that is, to the sets of characters supported encoded by each of the character sets.
By definition, character set A is a superset of character set B if A supports all characters that B supports.
Character set B is a subset of character set A if A is a superset of B. The terms binary subset and binary superset restrict the above subset-superset relationship by adding a condition on binary representation binary codes of characters of the two character sets.
By definition, character set A is a binary superset of character set B if A supports all characters that B supports and all these characters have the same binary representation in A and B. Character set B is a binary subset of character set A if A is a binary superset of B.
When character set A is a binary superset of character set B, any text value encoded in B is at the same time valid in A without need for character set conversion.
When A is a non-binary superset of B, a text value encoded in B can be represented in A without loss of data but may require character set conversion to transform the binary representation.
Oracle Database does not maintain a list of all subset-superset pairs but it does maintain a list of binary subset-superset pairs that it recognizes in various situations such as checking compatibility of a transportable tablespace or a pluggable database.
Table A and Table A list the binary subset-superset pairs recognized by Oracle Database Length Semantics In single-byte character sets, the number of bytes and the number of characters in a string are the same.
In multibyte character sets, a character or code point consists of one or more bytes. Calculating the number of characters based on byte lengths can be difficult in a variable-width character set.
Calculating column lengths in bytes is called byte semantics, while measuring column lengths in characters is called character semantics. Character semantics is useful for defining the storage requirements for multibyte strings of varying widths.
Using byte semantics, this column requires 15 bytes for the Chinese characters, which are three bytes long, and 5 bytes for the English characters, which are one byte long, for a total of 20 bytes.
Using character semantics, the column requires 10 characters. The following expressions use byte semantics: The following expressions use character semantics: This method of specifying the length semantics is recommended as it properly documents the expected semantics in creation DDL statements and makes the statements independent of any execution environment.
Its default value is BYTE. For the sake of compatibility with existing application installation procedures, which may have been written before character length semantics was introduced into Oracle SQL, Oracle recommends that you leave this initialization parameter undefined or you set it to BYTE.
Otherwise, created columns may be larger than expected, causing applications to malfunction or, in some cases, cause buffer overflows. Byte semantics is the default for the database character set. Character length semantics is the default and the only allowable kind of length semantics for NCHAR data types.
Consider the following example: Figure shows the number of bytes needed to store different kinds of characters in the UTF-8 character set.A photo collection gathered from ordinary objects that create ph-vs.com Art Photography including name frames is a growing trend in home décor.
