Does JSON have to be UTF-8?
Previous specifications of JSON have not required the use of UTF-8 when transmitting JSON text. However, the vast majority of JSON-based software implementations have chosen to use the UTF-8 encoding, to the extent that it is the only encoding that achieves interoperability.
Is JSON encoded?
Decoding JSON Data in PHP
Decoding JSON data is as simple as encoding it. You can use the PHP json_decode() function to convert the JSON encoded string into appropriate PHP data type.
Should I always use UTF-8?
When you need to write a program (performing string manipulations) that needs to be very very fast and that you’re sure that you won’t need exotic characters, may be UTF-8 is not the best idea. In every other situations, UTF-8 should be a standard. UTF-8 works well on almost every recent software, even on Windows.
Is JSON UTF-8 or UTF 16?
(in Introduction) JSON text is a sequence of Unicode code points. The earlier RFC4627 stated that, (in §3) JSON text SHALL be encoded in Unicode. The default encoding is UTF-8.
Is JSON ASCII or UTF-8?
The default encoding is UTF-8, and JSON texts which are encoded in UTF-8 are interoperable in the sense that they will be read successfully by the maximum number of implementations; there are many implementations which cannot successfully read texts in other encodings (such as UTF-16 and UTF-32).
Is JSON easy to learn?
Is JSON a database?
A JSON document database is a nonrelational database designed to store and query as JSON documents. JSON data in the database is textual, but the text can be stored using data type BLOB , VARCHAR2 , CLOB , or binary JSON data type in 21c.
Why UTF-16 is bad?
The main hazard of UTF-16 is that it leads to people believing they are handling unicode correctly, when often they don’t properly decode surrogate pairs, etc. Between UTF-8 and UTF-32, the only use for UTF-16 is in legacy systems.
Does UTF-8 support all languages?
UTF-8 supports any unicode character, which pragmatically means any natural language (Coptic, Sinhala, Phonecian, Cherokee etc), as well as many non-spoken languages (Music notation, mathematical symbols, APL). The stated objective of the Unicode consortium is to encompass all communications.
How do I pass a Unicode character in JSON?
All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F). Any character may be escaped.
Is UTF-8 and ascii same?
UTF-8 encodes Unicode characters into a sequence of 8-bit bytes. … Each 8-bit extension to ASCII differs from the rest. For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration.
Can JSON handle Unicode?
The JSON specification states that JSON strings can contain unicode characters in the form of: “here comes a unicode character: u05d9 !“
