When the system locale is set to pt-BR, the date displayed in the top or bottom panel includes a comma between the abbreviated month and the time, resulting in two consecutive punctuation marks: 25 de abr., 09:35.

The vertical layout is not affected because it formats date and time separately.

The horizontal layout, however, combines them via ICU4X's datetime combining pattern for pt-BR, which appears to be "{1}, {0}" (comma-separated) instead of "{1} {0}".

The . is correct, it belongs to the abbreviated month (abr.).

The problem is the , that ICU4X inserts as a separator between the date and time parts, producing the awkward ., sequence which is not natural in Brazilian Portuguese.

Steps to reproduce

1. Set system locale to pt-BR
2. Set Panel Position on screen to Bottom or Top

Expected behavior

25 de abr. 09:35 with no comma between date and time.

Proposed fix

Strip the combining comma from the formatted string for pt-BR, or format date
and time separately and concatenate with a space, similar to what the vertical
layout already does.

I only need to know if in some other language this comma is necessary by some reason.

I only need to know if in some other language this comma is necessary by some reason.

It's necessary for English, so we can't accept the PR in its current form. This is the before/after:

Removing the comma leaves numbers separated by no punctuation, which we generally need to avoid. Any change to the current comma would need to be approved by the UX team.

A fix specific to your language could potentially be accepted. It seems weird we'd use an internationalization formatter and then have to touch up the result, though. Is it possible this is something that could be improved upstream in ICU4X instead of specifically in this applet?
