When printing to the console, Python looks at sys.stdout.encoding to determine the encoding to use to encode unicode objects before printing. When redirecting output to a file, sys.stdout.encoding is None, so Python2 defaults to the ascii encoding. (In contrast, Python3 defaults to utf-8.) This often leads to an exception when printing unicode. You can avoid … Read more
Unicode has two symbols for unknown characters: □ (WHITE SQUARE, U+25A1) – Replaces a missing or unsupported Unicode character. � (REPLACEMENT CHARACTER, U+FFFD) – Replaces an invalid or unrecognizable character. Indicates a Unicode error. Sources Quora – What symbol is the square box shown for non-representable Unicode characters? FileFormat.Info – Unicode Character ‘WHITE SQUARE’ (U+25A1) … Read more
It’s not exactly that ncurses is broken. More like, glibc is broken. Or whatever implementation of libc you are using; I’m just assuming that it is glibc. Unlike simple console output (i.e., printf), ncurses needs to know how wide every character is when it is printed because it needs to maintain its own model of … Read more
int(limit) returns the value converted into an integer, and doesn’t change it in place as you call the function (which is what you are expecting it to). Do this instead: limit = int(limit) Or when definiting limit: if ‘limit’ in user_data : limit = int(user_data[‘limit’])
Try: nonascii() { LANG=C grep –color=always ‘[^ -~]\+’; } Which can be used like: printf ‘ŨTF8\n’ | nonascii Within [] ^ means “not”. So [^ -~] means characters not between space and ~. So excluding control chars, this matches non ASCII characters, and is a more portable though slightly less accurate version of [^\x00-\x7f] below. … Read more
It can be done by opening the file using open(), which supports Unicode as in the linked answer, read the contents as a byte array, convert the byte array to a NumPy array, decode the image # -*- coding: utf-8 -*- import cv2 import numpy stream = open(u’D:\\ö\\handschuh.jpg’, “rb”) bytes = bytearray(stream.read()) numpyarray = numpy.asarray(bytes, … Read more
— is wrong. When you use numeric character references, the number refers to the Unicode codepoint. For numbers below 256 that is the same as the codepoint in ISO-8859-1. In 8859-1, character 151 is amongst the “C1 control codes”, and not a dash or any other visible character. The confusion arises because character 151 is … Read more
Use · · for a dot or • • for a thicker, bulleted list style dot. For use in the content attribute, you’ll need to escape it: middot: content: ” \B7 “; bull: content: ” \2219 “; Refrences: Adding HTML entities using CSS content 24.2.1 The list of characters – Character entity references in HTML … Read more
raw_input() returns strings as encoded by the OS or UI facilities. The difficulty is knowing which is that decoding. You might attempt the following: import sys, locale text= raw_input().decode(sys.stdin.encoding or locale.getpreferredencoding(True)) which should work correctly in most of the cases. We need more data about not working Unicode comparisons in order to help you. However, … Read more
There is no magic here – The C language gives you acess to the raw bytes, as they are stored in the computer memory. If your terminal is using utf-8 (which is likely), non-ASCII chars take more than one byte in memory. When you display then again, is our terminal code which converts these sequences … Read more
