meaning that encoding errors raise UnicodeError. Other possible values are 'ignore', 'replace' and any other name registered via codecs.register_error(), see section Codec Base Classes
Encoding is the process of converting Unicode codepoints into binary data that can be written or transmitted by a computer system. Javascript strings are encoded in UTF-16, meaning every character takes up 16 bits, or 2 bytes (there are 8 bits per byte). The problem is that not every ...
Index values refer to char code units, so a supplementary character uses two positions in a String. The String class provides methods for dealing with Unicode code points (i.e., characters), in addition to those for dealing with Unicode code units (i.e., char values). Unless otherwise...
Within a string, certain sequences have special meaning unless the NO_BACKSLASH_ESCAPES SQL mode is enabled. Each of these sequences begins with a backslash (\), known as the escape character. MySQL recognizes the escape sequences shown in Table 9.1, “Special Character Escape Sequences”. Fo...
The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be relied upon to always remain the same. For more information, see the section Code Model ...
To include a brace, "{" or "}", in the text produced by an interpolated string, use two braces, "{{" or "}}". For more information, see theEscaping bracessection of theComposite formattingarticle. As the colon (":") has special meaning in an interpolation expression item, to use ...
The correctness of the arguments is determined by the language behind the code model. 备注 The values of code model elements such as classes, structs, functions, attributes, delegates, and so forth can be non-deterministic after making certain kinds of edits, meaning that their values cannot be...
The dollar sign$has also a special meaning in PHP; it denotes a variable. If a variable is used inside a string, it is interpolated, i.e. the value of the variable is used. To echo a variable name, we escape the$character\$. ...
