unicode

问题 I have a small console based application that will solve physics equations. I am trying to ask the user if they want to find the ΔV in a given situation, but I can't figure out how to print the letter delta to the console. Here's my code: cout << "Select what you would like to find:\n" << "1 - Acceleration" << endl << "2 - Initial Velocity" << endl << "3 - Final Velocity" << endl << "4 - ΔV" << "\n\n"; cin >> choice; This does not print "ΔV" to the console. The "Δ" doesn't even display in my

问题 I am currently trying to parse UnicodeData.txt with this format: ftp://ftp.unicode.org/Public/3.0-Update/UnicodeData-3.0.0.html However, I am hitting a problem in that when I try to read, say a line like the following. something;123D;;LINE TABULATION; I try to get the data from the fields by code such as the following. The problem is that fields[3] is not getting filled in, and scanf is returning 2. in is the current line. char fields[4][256]; sscanf(in, "%[^;];%[^;];%[^;];%[^;];%[^;];",

问题 I have seen Questions and Answers about obtaining the code point number of a Unicode character in Java. For example, the Question How can I get a Unicode character's code?. But I want the opposite: given an integer number, how do I get text of that character assigned to that code point number? The char primitive data type is of no use, being limited to only the Basic Multilingual Plane of the Unicode character set. That plane represents approximately the first 64,000 characters defined in

问题 I am writing a forum in Python. I want to strip input containing the right-to-left mark and things like that. Suggestions? Possibly a regular expression? 回答1: If you simply want to restrict the characters to those of a certain character set, you could encode the string in that character set and just ignore encoding errors: >>> uc = u'aäöüb' >>> uc.encode('ascii', 'ignore') 'ab' 回答2: The OP, in a hard-to-read comment to another answer, has an example that appears to start like...: comment =

问题 For context, I have a form in my ReactJS app and I submit: Awp ACq smr`Q pRBu deI bfweI nwm [ My API ends up saving that value in the database as the following value: Awp ACq smr`Q pRBu deI bfweI nwm [ However, when I go to display this in the my React app, it renders the following: This is what (I think) it should be: How can I correctly display this content in React? It feels like I am doing something wrong by the lack of sources I could find: React Javascript displaying/decoding unicode
