I have a program for a Blackjack game. It is not completed but I am having an issue with Unicode. When it prints a string it is not in the correct format (Look Below). It is Python 3.

from unicurses import * import sys import time from random import choice as rc import random def total(hand): #total aces = hand.count(11) t = sum(hand) if t > 21 and aces > 0: while aces > 0 and t > 21: t -= 10 aces -= 1 return t def random(one,two): import random number = random.randint(one,two) return number def number(): number = random(1,13) if number == 13: value = '0' elif number == 12: value = '0' elif number == 11: value = '0' elif number == 10: value = '0' elif number < 10: value = number return value def card(): cardnumber = number() card = cardnumber return card def store10Cards(): tenCards = [card(), card(), card(), card(), card(), card(), card(), card(), card(), card()] return tenCards stdscr = initscr() cards = store10Cards() mvaddstr(10, 10, '┌──────────┐\n│{} │\n│ │\n│ │\n│ │\n│ │\n│ │\n│ │\n│ │\n│ {}│\n└──────────┘'.format(cards[0], cards[0]).encode('utf-8')) #deck = [] #deck of cards #cwin = 0 #computer wins #pwin = 0 #player wins #for i in range (2, 11): # for j in range ([24, 72][i == 10]): # deck.append(i) #stdscr = initscr() #Start the standard screen start_color() #Start the color service init_pair(1, COLOR_RED, 0) #color pair 1 is red text and no highlighting init_pair(2, COLOR_WHITE, 0) #color pair 2 is white text and no highlighting addstr('\n\n------------------------------------------------------------------------', color_pair(1) | A_BOLD) addstr('\n\n\nAre You Ready To Try And Defeat The Undefeated Blackjack Master?\n\n\nThe First One To Win 10 Hands Wins!!!\n\n\nAces Are Counted As 11s And Automaticlly Change To 1 If You Go Over 21. \n\n\nWinning 1 Hand Does Not Mean You Win The Game\n\n\nIt Is Possible To Win But Very Hard!!!

Here is the line I am having issues with:

mvaddstr(10, 10, '┌──────────┐\n│{} │\n│ │\n│ │\n│ │\n│ │\n│ │\n│ │\n│ │\n│ {}│\n└──────────┘'.format(cards[0], cards[0]).encode('utf-8')) 

I tried to encode it with UTF-8 and set Command Prompt to UTF-8 by doing chcp then when I run that program that string prints:

b'\xe2\x94\x8c\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\x e2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x90\n\xe2\x94\x823 \xe2\x94\x82\n\xe2\x94\x82 \t \xe2\x94\x82\n\xe2\x94\x82 \t \xe2 \x94\x82\n\xe2\x94\x82 \t \xe2\x94\x82\n\xe2\x94\x82 \t \xe2\x94\x82\n\x e2\x94\x82 \t \xe2\x94\x82\n\xe2\x94\x82 \t \xe2\x94\x82\n\xe2\x94\x82 \t \xe2\x94\x82\n\xe2\x94\x82 3\xe2\x94\x82\n\xe2\x94\x94\xe2\x94\x80\xe 2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\x94\x80\xe2\ x94\x80\xe2\x94\x80\xe2\x94\x98'

Please help me print the string like it should be and not be in unicode.

If you have any other suggestions on my code let me know.

  • What is the encoding of your source file? Commented Aug 7, 2016 at 22:22
  • You are printing bytes, producing their debugging representation. Decode the bytes first. Commented Aug 7, 2016 at 22:29

On Windows, unicurses uses ctypes to wrap PDCurses. This library is optionally built with Unicode support in the 32-bit DLLs that are distributed on the project site. FYI, the Unicode versions call console wide-character APIs such as WriteConsoleOutputW, so don't worry about the legacy console codepage. You need the "pdc34dllu.zip" build, which takes UTF-8 encoded parameters. Because the pre-built DLLs are only 32-bit, you'll have to use 32-bit Python, unless you have Visual Studio 2015 installed to build a 64-bit DLL.

You'll also have to make a couple of changes to unicurses to make this work. Here are the steps I followed to get this working for 32-bit Python 3.5:

  1. Download pdc34dllu.zip. Extract "pdcurses.dll" to either Python's installation directory, i.e. where python.exe is located, or to a directory that's in the PATH environment variable.
  2. Download and extract UniCurses-1.2.zip.
  3. Before installing, make the following changes to unicurses.py. On line 34 change code = locale.getpreferredencoding() to code = 'utf-8'. Next, comment out lines 52-54, which start with if not os.access("pdcurses.dll",os.F_OK) because this check will always fail if "pdcurses.dll" isn't in the working directory.
  4. Install the package by running python setup.py install.

example: printing a card

import unicurses card_template = '\n'.join([ '┌────────────┐', '│{card} │', '│ │', '│ │', '│ │', '│ │', '│ │', '│ │', '│ │', '│ {card}│', '└────────────┘']) def main(): stdscr = unicurses.initscr() unicurses.clear() card_string = card_template.format(card=5) for i, line in enumerate(card_string.splitlines()): unicurses.mvaddstr(5 + i, 5, line) unicurses.refresh() unicurses.endwin() if __name__ == '__main__': main() 

output

 ┌────────────┐ │5 │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ 5│ └────────────┘

You are the best! Thank you so much. I had to edit your code because I want multiple cards next to each other but it worked. Thanks!
