I am in Calgary (Canada) and, certainly, agree w/ y'all.
If it is any consolation at all for many countries this will not, any longer, be the case come Spring of 2018.
Already, in the Insider Builds, it works w/out being set to English (US). Suggest you will see this change (improvement) in the major Spring update on mainstream installations. Ergo, not a very long wait to endure, now.
Case in point, I am running my 1709 w/ English (US) whilst, my IB is English (Canada) and Emoji Panel works in both.
We did know @ the onset that it would be, initially, English (US) only & broaden sometime thereafter.
Cheers,
Drew
