Move ± from Portuguese to Special Characters in Quick Accent

[bveldkamp]

Description of the new feature / enhancement

After I unchecked many languages I don't use in Quick Accent, I found that the plus-minus (±) sign (under the comma key) has disappeared. When I checked the code, I found that it is only included in the Portuguese character set. I am curious about what makes ± Portuguese only.
On the other hand, the ∓ character is included in 'Special characters', and can be access through the + key. I think it makes sense to have ± there as well.

Can ± be moved (or copied to) Special characters, and be made accessible with the + key?

Scenario when this would be used?

• This would be useful for everyone who does not use Portuguese, but still wants to type ±
• I don't use ± often enough to remember it's under the comma key. Having it under + as well would save me from searching for it

I noticed there's more than just the ± sign: In the Portuguese character definition (GetDefaultLetterKeyPT()) there is LetterKey.VK_COMMA => new[] { "≤", "≥", "≠", "≈", "≙", "±", "₊", "⁺" },, which I think is strange. None of these characters are specific to that language, and to have them under the , key is somewhat arbitrary. Most of them are also included in Special Characters, except ±, ₊ and ⁺.

I'd like to propose moving these three to Special Characters as well, and remove them from Portuguese
