我应该如何在数组中使用盲文字母来绘制AsciiArt？

问题描述

这是我的代码

from PIL import Image

ASCII_CHARS = ["@","#","$"," ","-","|",":","."," " ]

def resize_image(image,new_width=50):
    width,height = image.size
    ratio = height/width
    new_height = int(new_width * ratio)
    resized_image = image.resize((new_width,new_height))
    #resized_image.save('output.png')
    return(resized_image)

def grayify(image):
    grayscale_image = image.convert("L")
    #grayscale_image.save('output.png')
    return(grayscale_image)

# convert pixels to a string of ascii characters
def pixels_to_ascii(image):
    pixels = image.getdata()
    characters = ''.join([ASCII_CHARS[pixel//25] for pixel in pixels])
    return(characters)

def main(new_width=50):
    # attempt to open image from user-input
    #path = input("Enter a valid pathname to an image:\n")
    try:
        image = Image.open("picachu.jpg")
    except:
        print(path," is not a valid pathname to an image.")
        return

    # convert image to ascii
    new_image_data = pixels_to_ascii(grayify(resize_image(image)))

    # format
    pixel_count = len(new_image_data)
    ascii_image = '\n'.join([new_image_data[index:(index+new_width)] for index in range(0,pixel_count,new_width)])


    with open("full_image.txt","w") as f:
        f.write(ascii_image)

    fa = open("full_image.txt","r")
    fb = open("trimmed_image.txt","w")
    lines = fa.readlines()
    fa.close()
    lines = filter(lambda x: not x.isspace(),lines)
    fb.write("".join(lines))
    fb.close()

main()

对于picachu.jpg输出如下：

                             |-                   
                             $                    
                            |#$                   
                             ##.

          ................:   .::|.    .:|::      
          :................ |::.:|                
         .................: :|:.|.                
         .................: :||:|                 
         :..................: -                   
         :.................- $-                   
        ...................:  -                   
        :....................                     
        :....................                     
        :..........::::::...:                     
        .::::::::::||||||::..

        :::|||.     ..::|-|::|.

       ..                     ..                  

因此，代码没有问题！但问题是我想使用盲文字母“⡿⡾⡹⡲⡱⠶⠷⠸”而不是“ @＃|-等” 当我尝试时：

ASCII_CHARS = ["\u280F"," "]

它给了我这个错误UnicodeEncodeError: 'charmap' codec can't encode character '\u280f' in position 317: character maps to <undefined>

有人知道如何解决此问题吗？ 您可以找到其他盲文字符Unicode和十进制代码here
