Handling colon behaviour between languages (English and French)?

[ajmas]

We have a bilingual English/French website and we use the same message for both the table variant of a view and for a form variant. For the form view a field uses a colon, though there is an expected difference between the way French and English expect them to behave. In English the colon is stuck to the label, while in French a space is expected between the label and the colon:

• My Label:
• My Label :

Beyond rolling our own function for this, I am curious whether something exists out of the box for this, that I might have missed in the documentation?

Note, if we weren't re-using the label for the column headers, then we would simply throw in the colon into the text.

One approach I am looking at (though not sure if there is a better solution):

messages = {
  'field.label': '{text} :',
  'label.name': 'name'
}

function fieldLabel(key: string) {
  return t('field.label', { text: t(key) });
}
