Convert characters to Ascii

Question

Is there a twig filter to encode special characters like umlauts: {{ entry.title | filter }}

Datensätze & Karten

Which then should result in:

datensaetze-karten

Basically what 'convertFilenamesToAscii' => true, does but as a filter.

I want to use this as a anchorlink later on so umlauts are not the best to have in anchor links.

Answer 1

I would use a combination of things:

• Twig's replace filter to convert ä to ae etc.
• Twig's convert_encoding filter to eliminate any remaining non-ascii characters
• Craft's kebab filter to do its thing

and of course wrap the thing up in a macro

{% macro ascii_kebab(s) %}
  {{ s
    | replace({
        'ä': 'ae'
      })
    | convert_encoding('ASCII', 'UTF-8')
    | kebab
  }}
{% endmacro %}

Answer 2

You can use Craft's |ascii Twig Filter, which was added in Craft 3.1.25, for this:

{{ entry.title|ascii }}
