As mentioned by my colleague, this is a pretty universal thing, which we won't be changing.
I have to be honest here too, and say you should really ask yourself how much of an impact on the success of your site changing around a few emojis is going to make. We do see people overthink quite often, and it can be helpful to sit back at times and ask yourself if these things are really worth it.
Take this one thing as an example. We wont be implementing it ourselves. Evaluate if the below is worthwhile, or if it would be better spent on the sites content
Time spent here figuring out if it's possible
Time to write the relevant changes to do what you wish to do
Time fixing issues with what you just changed
Time updating these items on-site upgrades which break your changes
Time chasing what you think may be bugs due to those changes
Of course you may read the above and think "Yes!". If that's the case, then great! But it would be remiss of me not to share my thoughts.
