Feature request: localization

[Hadeer-Attalluh]

if we can add locale attribute to display percentage with different locale " specially Arabic " that would be great

[Hadeer-Attalluh]

for now i'm using a workaround where i set these attributes
[showTitle]="true"
[showSubtitle]="false"
[title]="{{localizednumberValue}}"

Better would probably be to allow ng-templates for subtitle, title and units params; then we can use whatever we want as text; it being localised or not.
