Two problems in Yosemite in French: Spotlight and Ctrl + More, how to fix them?

My OS is in French.

1) I open Spotlight and converted any currency to ARS (Argentinean peso), but Spotlight doesn't recognise this currency. It doesn't recognise AR, ARS, $AR, $ARS, Argentinean peso, peso argentin, etc.

2) In Pages and any applications, when I pressed Ctrl + More to increase the letter size, it aligned the text to center.

I switched OS X's language to English:

1) It isn't solved yet either. Spotlight doesn't recognise really this currency.

2)I t works, it doesn't align the text to center, it only increases the letter size.
