Comment:

 It's explicitly
 [https://docs.djangoproject.com/en/stable/ref/templates/builtins/#stringformat
 documented] that `stringformat`:

 > ''Formats the variable according to the argument, a **string formatting
 specifier**. This specifier uses the **printf-style String Formatting
 syntax**, with the exception that the leading “%” is dropped.''

 and in Python docs you will find that `.` is always used as a decimal
 separate. `localize/unlocalize` doesn't affect strings so everything works
 as expected.

 The stringformat filter breaks the numeric localization in the template.

 With these settings

 {{{
 LANGUAGES = [
 ("de", _("German")),
 ("en", _("English")),
 ]
 LANGUAGE_CODE = "de"
 TIME_ZONE = "Europe/Berlin"
 USE_I18N = True
 USE_TZ = True
 }}}

 the following template

 {{{
 {{ 3.14 }}
 {{ 3.14 | localize }}
 {{ 3.14 | unlocalize }}
 {{ 3.14159265359 | stringformat:".2f" }}
 {{ 3.14159265359 | stringformat:".2f" | localize }}
 {{ 3.14159265359 | stringformat:".2f" | unlocalize }}
 }}}


 Should print

 {{{
 3,14
 3,14
 3.14
 3,14
 3,14
 3.14
 }}}

 but factually prints

 {{{
 3,14
 3,14
 3.14
 3.14 <--
 3.14 <--
 3.14
 }}}
