In symfony project, I would like to use an underscore as a separator for the parameter in routing.yml.

Url example: /article/lorem-1111_45.html

In routing.yml

rule_sample:
 url:      /article/:info-:datePublished_:id.html
 param:    { module: cms, action: test }
 options:
   segment_separators: ['-', '/', '.', '_']
 requirements:
   info: ^([A-Za-z0-9\-]+)$
   datePublished: \d+
   id: \d+

This code doesnt work. I have the following error: Unable to parse "/article/:info-:datePublished_:id.html" route near ":id.html".

Anybody knows how to implement this rule ?
