A character when preceded by a “\” i.e. backslash (that adds specifies meaning to the compiler) is Java Escape Sequence or Escape Character. There are some commonly used Java escape characters that will be discussed in the next segment. The Java compiler interprets this series of characters...
文中主要讨论了"character set"与"转义序列"（escape sequence）的概念，以及它们在不同编程语言和文本处理环境中的应用。首先，"escape"这一术语在技术语境中可能引起混淆，因此需要通过例子来澄清。例如，在描述HOME键时，"escape"可以由"sequence"表示，仿佛我们依次输入字符。在特定终端如VT100中，功能...
这就要说到HTML转义字符串(Escape Sequence)了。 转义字符串(Escape Sequence)也称字符实体(Character Entity)。在HTML中,定义转义字符串的原因有两个:第一个原因是像“<”和“>”这类符号已经用来表示HTML标签,因此就不能直接当作文本中的符号来使用。为了在HTML文档中使用这些符号,就需要定义它的转义字符串。当解...

Escape sequences allow you to send nongraphic control characters to a display device. For example, the ESC character (\033) is often used as the first character of a control command for a terminal or printer. Some escape sequences are device-specific. For instance, the vertical-tab and for...
An addition of the string/character escape sequence \e as a shortcut/short-hand replacement for the character code point 0x1b, commonly known as the ESCAPE (or ESC) character. This character is currently accessible using one of the following escape sequences: \u001b \U0000001b \x1b (not...
C# defines the following character escape sequences:\' - single quote, needed for character literals \" - double quote, needed for string literals \\ - backslash \0 - Unicode character 0 \a - Alert (character 7) \b - Backspace (character 8) \f - Form feed (character 12) \n - New...
Character combinations consisting of a backslash (\) followed by a letter or by a combination of digits are called "escape sequences." To represent a newline character, single quotation mark, or certain other characters in a character constant, you must use escape sequences. An escape sequence...
