问题 I want to sort some letters in ts... sort method and localCompare() sort in this way Ä, Å, Ö, instead of Å, Ä, Ö. How to sort any letters corectly?

问题 I have a query select * from table where name in ('52 T&M', '60 T&M'); The "&" is causing the query to expect a parameter. How do I qualify the "&" in the query to sting so that the query can find string with the "&" character in them? 回答1: I would normally use set define off as suggested by omg but it is also possible to do it like this: select * from table where name in ('52 T'||Chr(38)||'M', '60 T'||Chr(38)||'M'); 回答2: The ampersand ("&") is a character interpreted by SQLPlus as a variable

问题 I've finished my poker game but now I want to make it look a bit better with displaying Spades, Hearts, Diamonds and Clubs. I tried this answer: C++: Printing ASCII Heart and Diamonds With Platform Independent Maybe stupid but I try: cout << 'U+2662' << endl; I don't know how to write it. 回答1: To output a UTF-8 character, you need to encode it as hex bytes. I'll steal this link to fileinfo.com from an answer to the question you linked - if you jump to the UTF-8 representation, it says 0xE2

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago .

问题 I'm developing a web application where users have profiles, and skills related to that profile. I want to develop a page where a user can see all profiles that correspond to a particular skill.

问题 When adding a string that might contain troublesome characters (eg &, <, >), DOMDocument throws a warning, rather than sanitizing the string. I'm looking for a succinct way to make strings xml-safe - ideally something that leverages the DOMDocument library. I'm looking for something better than preg_replace or htmlspecialchars . I see DOMDocument::createTextNode() , but the resulting DOMText object is cumbersome and can't be handed to DOMDocument::createElement() . To illustrate the problem,
