django does not allow form inputs in non-english languages - django

Question

I have an input in my form which I try to label in Russian, for example:
email = forms.CharField(label='ййй')
The problem occurs when the label contains only non-English characters, the label simply disappears.
Interestingly enough, when the label contains at least one English character, the label will appear, for example:
email = forms.CharField(label='йййa')
Works correctly.
The same problem occurs with attributes in the widget parameter
email = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'ййй'}))
This the template HTML code:
{% load widget_tweaks %}
<h2>Sign up</h2>
<form method="post">
{% csrf_token %}
{% for hidden_field in form.hidden_fields %}
{{ hidden_field }}
{% endfor %}
{% if form.non_field_errors %}
<div class="alert alert-danger" role="alert">
{% for error in form.non_field_errors %}
{{ error }}
{% endfor %}
</div>
{% endif %}
{% for field in form.visible_fields %}
<div class="form-group">
{{ field.label_tag }}
{% if form.is_bound %}
{% if field.errors %}
{% render_field field class="form-control is-invalid" %}
{% for error in field.errors %}
<div class="invalid-feedback">
{{ error }}
</div>
{% endfor %}
{% else %}
{% render_field field class="form-control is-valid" %}
{% endif %}
{% else %}
{% if field.name == 'birth_date' %}
{% render_field field class="form-control date" id="date" name="date" %}
{% else %}
{% render_field field class="form-control" %}
{% endif %}
{% endif %}
{% if field.help_text %}
<small class="form-text text-muted">{{ field.help_text }}</small>
{% endif %}
</div>
{% endfor %}
<button type="submit" class="btn btn-primary">Submit</button>
</form>
This is the output html code:
<h2>Sign up</h2>
<form method="post">
<input type='hidden' name='csrfmiddlewaretoken' value='Q2EvMWMCPrV597OQV8aqJwtC4X1zuSQI9oVdjeZtgzQUYTAYSp5v22cz2zfOZgwn' />
<div class="form-group">
<input type="text" name="email" autofocus required class="form-control" id="id_email" />
</div>
<div class="form-group">
<label for="id_id_num">Id number:</label>
<input type="text" name="id_num" id="id_id_num" required class="form-control" maxlength="9" />
</div>
<div class="form-group">
<label for="id_password1">Password:</label>
<input type="password" name="password1" required class="form-control" id="id_password1" />
<small class="form-text text-muted"><ul><li>Your password can&#39;t be too similar to your other personal information.</li><li>Your password must contain at least 8 characters.</li><li>Your password can&#39;t be a commonly used password.</li><li>Your password can&#39;t be entirely numeric.</li></ul></small>
</div>
<div class="form-group">
<label for="id_password2">Password confirmation:</label>
<input type="password" name="password2" required class="form-control" id="id_password2" />
<small class="form-text text-muted">Enter the same password as before, for verification.</small>
</div>
<div class="form-group">
<label for="id_first_name">First name:</label>
<input type="text" name="first_name" id="id_first_name" required class="form-control" maxlength="30" />
</div>
<div class="form-group">
<label for="id_last_name">Last name:</label>
<input type="text" name="last_name" id="id_last_name" required class="form-control" maxlength="30" />
</div>
<div class="form-group">
<label for="id_birth_date">Birth date:</label>
<input type="text" name="birth_date" required id="date" name="date" class="form-control date" />
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>

Found a solution, simply add "u" before the string to make it unicode
email = forms.CharField(label=u'ййй')
