ascii

问题 I am able to convert an NSString of (ASCII) text to a NSString of binary numbers, but I am having troubles doing the opposite. For example: "Hi" becomes "01101000 01101001". I need: "01101000 01101001" to become "Hi". I'm looking for the most direct way to implement this. Note the space between every 8 bits of binary numbers. 回答1: Considering the format is always like that, this code should work: NSString * BinaryToAsciiString (NSString *string) { NSMutableString *result = [NSMutableString

问题 in my app I need to get character from extended ASCII table that is shown on the image. But when I cast decimal values into char, I get different characters. What is the real value of these characters in JAVA. I dont write the character on console or in a file, just into the image. private void generateAsciiMatrix() { //32 - 255 are visible characters in ascii table for(int i = 32; i < 256; i++) { this.generateAsciiMatrix((char)i); } } private void generateAsciiMatrix(char letter) {

问题 Few posts ago somebody suggested me to look into Asciimatics library for Python. i'm trying to get my head around it, using: samples - https://github.com/peterbrittain/asciimatics/tree/master/samples documentation - https://asciimatics.readthedocs.io/en/stable/ Yet, as I'm novice, I'm still a bit confused about few quite basic things in it. I know, that by using effect array you can create layers of code that will overwrite information on the screen, based of their position in the array. The

问题 I spent about four hours researching the "UnicodeWarning: Unicode unequal comparison" issue. Usually, after a few hours, I'm able to answer my trickiest questions by myself, but that wasn't the case here. And I mean "tricky" for myself, of course. ;-) I know that similar questions are answered online and also on this site, but being too noob to understand the answer well doesn't help me at all. Maybe the best way for me to get it is just having someone point out what needs to be changed in my

问题 I am quite new to tensorflow, and I couldn't find what I wanted on tensorflow.org or online discussions. I have a tensor of ASCII codes I would like to convert to a string (each tensor is a word). In numpy I could just iterate and use chr(), but tensor object is not iterable. Is there a function that operates on the whole tensor, or a method that does not require evaluation? Thanks!

问题 I'm trying to display an emoji (ascii #55357) in CoreText and this is what I'm getting: It displays two of these characters and inserts the cursor in the middle. I'm not going to include my CoreText code because it's such a mess and I have no idea where the bug is originating from, but what I was just curious has anyone else seen the same problem before in any facet of iOS and what is the meaning of these sort of A in a black and white box characters that got displayed? Does it mean invalid

问题 This question already has answers here : Pygame: Is there any easy way to find the letter/number of ANY alphanumeric pressed? (2 answers) Closed last year . I have a Pygame program that needs text input. The way it does this is to get keyboard input and when a key is pressed it renders that key so it is added to the screen. Essentially it acts like a text field. The problem is, when you hold shift it doesn't do anything. I realize this is because the program ignores shift input and instead

问题 A comment on an earlier version of this answer of mine alerted me to the fact that I can't assume that 'A' , 'B' , 'C' etc. have successive numeric values. I had sort of assumed the C or C++ language standards guarantee that this is the case. So, how should I determine whether consecutive letter characters' values are themselves consecutive? Or rather, how can I determine whether the character constants I can express within single quotes have their ASCII codes for a numeric value? I'm asking

问题 I would like to be able to detect when the user: Inputs Japanese characters (Kanji or Kana) Inputs Roman characters (exclusively) Currently I am using the ASCII range like this (C# syntax): string searchKeyWord = Console.ReadLine(); var romajis = from c in searchKeyWord where c >= ' ' && c <= '~' select c; if (romajis.Any()) { // Romajis } else { // Japanese input } Is there a better, faster (stronger...) way to do this? EDIT: the question can be generalized to any other language with a non

问题 I have strings containing characters which are not found in ASCII; such as á, é, í, ó, ú; and I need a function to convert them into something acceptable such as a, e, i, o, u. This is because I will be creating IIS web sites from those strings (i.e. I will be using them as domain names). 回答1: function Convert-DiacriticCharacters { param( [string]$inputString ) [string]$formD = $inputString.Normalize( [System.text.NormalizationForm]::FormD ) $stringBuilder = new-object System.Text
