But some of the pages give me "malformed UTF-8 character in JSON string" error. I notice that the the last letter in "cafe" will produce error. I think it is because of the mix of character types. So now I'm looking for a way to convert all types of character to utf-8 (hope there is a way perfect like that). I tried utf8::all, it just doesn't work (maybe I didn't do it right). I'm a noob. Please help, thanks. UPDATA Well, after I read the

I get a value cda, which is defined in C as a double* (it is a pointer to a double array). When importing into Swift, it recognizes the type as UnsafeMutablePointer. I'm trying to convert this pointer and the count into a double array. Here's the code that I'm using (assume arrlen is the correct count of the array): let doublearrptr = UnsafePointer<Double>(cda) let xptarr = UnsafeBufferPointer<Double>(start: doublearrptr, count:arrlen) However, when compiling this code fragment, I get

How can I verify this? Details: The first value comes from a hardware board that calculates with 64-bits precision. The board sends the value to a PC, but it should also convert the value to 32-bits precision and send that to another board, which in turn sends it to a PC. I just want to verify that this is really happening and all I have

This is the command I tried using: LOAD DATA LOCAL INFILE 'c:/scheduletest.csv' INTO TABLE game FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' (`date`, `time`, `awayteam_id`, `hometeam_id`); but again, it wouldn't do the dates right. Is there a way I can have it

Thanks :) 回答1: you can cast a string as a binary if you are using a recent enough version of PHP. $binary = (binary)$string; (binary) casting and b prefix forward

The original image-data is a pygame Surface which needs to be converted to a PIL Image. Therefore I found the tostring-function of pygame which exists for that purpose. However the result looks pretty odd (see attached screenshot). What is going wrong with this code: rImage = pygame.Surface((1024,768)) #draw something to the Surface sprite = pygame.sprite.RenderPlain((playboard,)) sprite.draw(rImage) pil_string_image = pygame.image.tostring(rImage, "RGBA",False) pil_image =

Whose content would look like the following after converting 1.2345 00111111 11110011 11000000 10000011 00010010 01101110 10010111 10001101 In Java, there is a sollution that involves Double.doubleToLongBits() (A static method of java.lang.Double), but in Kotlin, Double refers to Kotlin.Double , which has no such (or any other useful in this situation) method. I don't mind if a sollution yields Kotlin.Double inaccessible in this file. :)

So when I grasp the generated svg, I could keep my the texts shapes. 回答1: There is no way in JavaScript (d3 or any other tool) to access the vector path information about the shape of individual letters in system or web fonts. It's a requested feature for SVG 2, but there are no firm proposals for how it would work. The Raphael method described in the question linked by Lars Kotthoff uses a font object that has already been converted to JavaScript, using the Cufon font
