slug with multiple languages

Using Django Forms & APIs
1

I have a model called ResourceFile defined similarly as so:

class ResourceFile(models.Model):
	BROCHURE, DATA_SHEET, APPLICATION_NOTE, TECHNICAL_NOTE = range(0, 4)
	RESOURCE_TYPES = (
		(BROCHURE, _("Brochure")),
		(DATA_SHEET, _("Data Sheet")),
		(APPLICATION_NOTE, _("Application Note")),
		(TECHNICAL_NOTE, _("Technical Note")),
	)

	file = models.FileField(_("File"), blank=True, null=True)
	title = models.CharField(_("Title"), max_length=255)
	resource_type = models.PositiveSmallIntegerField(
        _("Resource Type"), 
        choices=RESOURCE_TYPES
    )

The URL to view these resource_types is defined as so:

path(
        _("resources/<slug:resource_type>"),
        views.ResourceFileList.as_view(),
        name="resource-detail-list"
)

I am using two languages. resource_type is translated in Simplified Chinese using the .po and .mo files. I’m getting this error in the sitemap.xml:

NoReverseMatch at /sitemap.xml

Reverse for 'resource-detail-list' with keyword arguments
'{'resource_type': '手册s'}' not found. 1 pattern(s) tried:
['zh\\-hans/资源/(?P<resource_type>[-a-zA-Z0-9_]+)[\\Z](file://Z)']

Based on the error message, it becomes evident that the slug parameter used inside path does not take Unicode characters. Is there a reason for this limitation? Could I convince the Django Developers to change it and be more inclusive with the slug parameter? How does anyone else manage this issue?

The definition of slug in urls is clearly defined as a string of ascii characters or numbers (see URL dispatcher | Django documentation | Django).

If you want to allow any unicode character (except /), you can replace the slug converter by str
