Elements of Regular Expressions,ase of the plus sign, its special meaning is “additional characters like one just to the left of the + sign.” If you want to use any of these reserved characters as a literal in a regex, you need to escape them with a backslash. If you want to match 1+1=2, the correct regex is 1\+1=2. Otherwise, the作者: antenna 時(shí)間: 2025-3-22 11:42
Unicode,s less commonly used. Other representations of characters depend on the standard selected, which in turn may depend on the locale. As an example, consider the trademark sign.
