[yew-devel] [RFC PATCH yew-widget-toolkit-assets] flip font-awesome icons for rtl text direction

[Dominik Csapak]

when using a language that sets the text direction to RTL, font-awesome
icons that have left or right in the name are pointing in the wrong
direction, so flip them.

This happens for example in menus, back button of the material app,
list tiles where icons like 'chevron-right' are used, etc.

sending as rfc because i'm not sure this is the right approach.

alternatively we could create our own classes for every font-awesome
class that ends with -left/-right and call them -start/-end and
have only them flip in a rtl setting

Advantage would be that users could still use the 'left' and 'right'
variants if they need/want them.

i think i'd be in favor of this. there are already some approaches like
that out there [1]. it's clearer and sometime we may want an arrow to
always point left (or right) as pointed out by dietmar.
