Drawing characters and symbols

solub

Hi,

I'm trying to draw special characters / symbols with the text() function such as:

'■', '□', '▢', '▲', '△', '▼', '▽', '◆', '○', '●', 'Δ', 'ʊ', '™', '©', '®', '¿', '¡', '½', '⅓', '⅔', '¼', '¾', '⅛', '⅜', '⅝', '⅞', '℅', '№', '∃', '∩', '∀','Ξ', 'Γ', 'ɐ', 'ə', 'ɘ', 'ε', 'β', 'ɟ', 'ɥ', 'ɯ', 'ɔ', 'и', 'ɹ', 'ʁ', 'я', 'ʌ', 'ʍ', 'λ', 'ч', '∞', 'Σ', 'Π', 'η', 'α','·','¨','…', '¦', '┅', '┆', '┈', '┊',' ╱',' ╲', '╳', '¯', '–', '—','≡', '░', '▒', '▓', '█', '▌', '▐', '▀', '▄', '╭', '╮', '╯', '╰','│', '┤', '╡', '╢', '╖', '╕', '╣', '║', '╝', '╜',' ╛', '┐', '└', '┴', '┬', '├', '─', '┼', '╞', '╟', '╚', '╔', '╩', '╦', '╠', '═', '╬', '╧', '╨', '╤', '╥', '╙', '╘', '╒', '╓', '╫', '╪', '┘', '┌', 'Σ', '♠', 'Ω', '♣', '♥', '♦', '☼', '☻'...

However most of them (90%) don't seem to be recognized. All I have instead is the letter 'â' printed on the screen.

Is there a way to draw all these symbols ?

Thanks

Hey GoToLoop, thanks for your answer. Strangely, the code works in Java but not in Python mode.

    JAVA = 1/2 != 1/2.;
    FONT_SIZE = 24;
    FONT_JAVA = "Roman";

    def setup():
      size(600, 200)
      smooth(3)
      noLoop()

      colorMode(RGB)
      fill(20)

      textMode(MODEL)
      textAlign(CENTER, CENTER)

      if JAVA:
          textFont(createFont(FONT_JAVA, FONT_SIZE, True))
      else:
          textSize(FONT_SIZE)


    def draw():
      background(255)

      text("διχθαδίας κῆρας φερέμεν θανάτοιο τέλος δέ.\n" +
        "Бу́ря мгло́ю не́бо кро́ет, Ви́хри сне́жные крутя́;\n" + 
        "Ako sa voláš", width>>1, height>>1)

Any idea what could possibly prevent this to work in Python mode ?

Great ! Thank you GoToLoop.

Apologies @GoToLoop, I still have a problem regarding unicode text. I'm not writing text directly inside the text function (as in the example) but call an item randomly in a list of strings (here named "symbols"):

def setup():
    global x, y, edge, symbols
    background(240)
    size(706, 960)
    smooth(8)

    edge = 10
    x = 0
    y = edge
    symbols = ['■', '□', '▢', '▲', '△', '▼', '▽', '◆', '○', '●', 'Δ', 'ʊ']


def draw():
    global x, y

    x +=  edge
    if x >= width - edge:
        x = edge
        y += edge / 1.35
    if y >= height - (edge*2) and x >= width - (edge*2):
        noLoop()

    rdm = int(random(len(sym)))

    fill(0)
    text(u'%.s' % symbols[rdm], x, y)

The last line gives me the following error message:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: ordinal not in range(128)

Then I though this would do the trick:

text(u'%.s'.decode('utf-8') % sym[rdm], x, y)

But unfortunately I still get the same error message. Do you have an idea how to solve this problem in Python ?

Thanks a lot. :)
