来自tesseract的怪异角色

Question

当我在Windows 10上运行此python代码时：

from PIL import Image
import pytesseract
pytesseract.pytesseract.tesseract_cmd = 'C:/Program Files (x86)/Tesseract-OCR/tesseract'
im = Image.open("news.png")

text = pytesseract.image_to_string(im, lang='eng')

print(text.encode("utf-8"))

On this image.

我打印出来了：

为什么我得到这个奇怪的输出的任何想法，这是tesseract的限制还是我愚蠢？

谢谢，Ed。
