Question Help with scoreboards

[isaacwallace123]

I am currently making my own plugin with paper / spigot. My goal is to make an all-in-one economy plugin that allows users to connect to various database languages and to have full customization for their economy. I am currently in the process of making scoreboards that use placeholderapi to display certain characteristics pertaining to the player. I've made a scoreboard system using a dependency called "fastboard" to help me make the scoreboards. I would like to render unicode emojis as well as hexadecimal colors on the scoreboard. My configs look something like follows:

scoreboard:
  enabled: true
  hidden-by-default: false

  title: "<#FFFFFF>&l- Wall-Y.ca -</#FFFF00>"
  lines:
    - ""
    - "&4&l ^z^t&r Kills: &4%statistic_player_kills%"
    - "&6&l ^=^r^`&r Deaths: &6%statistic_deaths%"
    - "&a&l$&r Money: &a%vault_eco_balance_formatted%"
    - "&e&l ^o &r Playtime: &e%ptr_playtime_days%d %ptr_playtime_hours_trimmed%h"
    - "&9&l ^=^q &r Rank: %luckperms_suffix%"

All of the placeholders work, the issue is the hexadecimal in the title as well as the emojis "^z^t" like such. The goal is to replace keystroke emojis with the actual ones in game. I've seen TAB do exactly what my goal is though I'm not sure how.

Here is the code for my scoreboard handler. It gets instantiated in the main.
