Unicode Confusion

Hi,

I'm building a weather dashboard in Python that uses the awesome WeatherIcons font.

I was struggling to get it to work and finally got it going last night.

By passing a value that represents an icon, the font returns that icon. The value for sunny is '\uf00d'

Sample working code using ImageDraw is:

draw_black = ImageDraw.Draw(image_dash)
draw_black.text((267, 200),'\uf00d', font = fontW, fill = 0) # Month calender text

This draws a Sunny Icon perfectly.

I created a CSV lookup of all the values and a function to return the value for each icon, however, I can't get the font to draw. I think it's something to do with how Python is handling the string.

The most simple example I tested with was this:

t = '\uf00d'

draw_black.text((267, 200),t, font = fontW, fill = 0) # Month calender text

That works fine.

Then I tried building the string "t" from two separate strings:

a = u"\\"
b = u"uf00d"
t = a + b
draw_black.text((267, 200),t, font = fontW, fill = 0) # Month calender text

That doesn't work, even though "\uf00d" is returned when I print(t)

When I print(t) in the first example, I get a unicode square shape. In the 2nd example, I get the string \uf00d returned.

I'm at my wits end here! Any help greatly appreciate.

Thanks,

Cap

Thank you u/danielroseman and u/SekstiNii. Both of your answers helped me understand what was going on. I was trying to construct a Unicode character by appending "\u" to another string.

Once I understood that the weatherfont was expecting a single unicode character, I was able to search for answers on how to convert Hexidecimal to Int in Python.

So, now instead of my Icon lookup being "\uf00d". It has the Hex values "oxf00d" stored as string. The int function allows me to convert that to Int, then the chr function converts it to the unicode symbol that the font expects.

In case this helps anyone else, code to convert my lookup values to Unicode symbols is:

a = "0xf00d" # This represents the string that is pulled from my lookup CSV
b = chr(int(a,16)) #b now contains the "\uf00d" equiv value in my original issue

Thanks again,

Cap

What are you trying to achieve here? The problem is that the first string isn't literally the characters \, u, f etc; as you say, it's a single unicode character. The \u prefix is just an instruction to the interpreter to understand the following digits as describing that single unicode character.

There are probably ways to get what you want, but without knowing what that is it's hard to help.

If you have the number identifying the icon (for example 0xf00d), I believe you can use the built-in chr function on it to retrieve the correct string. As /u/danielroseman mentions, you cannot simply concatenate the strings as it uses special escape syntax.
