"Unicode Blank Symbol Rendering Issue after Updating to Python 3.11 and Django 4.1.7"

Question

I'm facing an issue with rendering a Unicode blank symbol in my Django project after upgrading to Python 3.11 and Django 4.1.7. Previously, I was using the following code snippet in my MyForm class:

from django import forms

class MyForm(forms.ModelForm):
    class Meta:
        model = mymodel
        labels = {
            "test": "​",
        }

The purpose of using "​" was to maintain formatting due to its equivalent height as a normal character.

However, since updating to Python 3.11 and Django 4.1.7, the Unicode blank symbol is no longer displayed correctly. Instead, it's being shown as the string "​".

I'd appreciate any insights into how I can resolve this issue. Thank you i```n advance for your help.

Best regards, tux

Answer 1

the solution is very easy, just use real python unicode coding instead of the html unicode. The reason why it crashed was, that Django is rendering the & to &. So the ​ is a ​ and the browser writes this sting: ​

here my solution which works:

from django import forms

class MyForm(forms.ModelForm):
    class Meta:
        model = mymodel
        labels = {
            "test": "\u200B",
        }
