Reason: (start off simple) So a tag at e621 is spades_(suit) : https://e621.net/wiki_pages/show_or_new?title=spades_%28suit%29

So I tried to add spades_(suit) to a e6ai post (post #85358 "Rating: EXPLICIT" ) and result was
"Can't add tag ♠: Name '♠' must consist of only ASCII characters."

♠, ♣, ♦ all imply to suit_symbol,
so as TESTs
a) i tried to add ♣ tag and got simillar result "Can't add tag ♣: Name '♣' must consist of only ASCII characters."
b) i tried to add ♦ tag and result was "Can't add tag ♦: Name '♦' must consist of only ASCII characters."

At (parent-site) e621 the tags that imply to suit_symbol are: clubs_(suit), diamonds_(suit), and spades_(suit).

{The 4th suit tag at e621 is hearts_(suit) }

So the aim of this BUR (BUR 1 of 2?) is to switch tags:
from ♣ TO clubs_(suit)
from ♦ TO diamonds_(suit)
from ♠ TO spades_(suit)

Tags that alias to ♣ : club_(suit), club_suit, clubs_(suit), clubs_suit
Therefore:
unalias club_(suit) -> ♣
unalias club_suit -> ♣
unalias clubs_(suit) -> ♣
unalias clubs_suit -> ♣

( for upcoming BUR : alias tags to clubs_(suit) )

*

Tags that alias to ♦ : <>, diamond_(suit), diamond_suit, diamond_symbol, diamonds_(suit), diamonds_suit
Therefore:
unalias <> -> ♦
unalias diamond_(suit) -> ♦
unalias diamond_suit -> ♦
unalias diamond_symbol -> ♦
unalias diamonds_(suit) -> ♦
unalias diamonds_suit -> ♦

( for upcoming BUR : alias tags to diamonds_(suit) )

*

Tags that alias to ♠ : spade_(suit), spade_suit, spades_(suit), spades_suit
unalias spade_(suit) -> ♠
unalias spade_suit -> ♠
unalias spades_(suit) -> ♠
unalias spades_suit -> ♠

( for upcoming BUR : alias tags to spades_(suit) )

and finally
unimply ♠ -> suit_symbol
unimply ♣ -> suit_symbol
unimply ♦ -> suit_symbol

( for upcoming BUR : alias tags {clubs_(suit), diamonds_(suit) and spades_(suit) } TO suit_symbol )

Posted forum thread "BUR UNalias and UNimply don't work? BUR bug?"
at topic #362

part 2 BUR (if BUR system fixed):
alias ♣ -> clubs_(suit)
alias club_(suit) -> clubs_(suit)
alias club_suit -> clubs_(suit)
alias clubs_suit -> clubs_(suit)
implicate clubs_(suit) -> suit_symbol
alias ♦ -> diamonds_(suit)
alias <> -> diamonds_(suit)
alias diamond_(suit) -> diamonds_(suit)
alias diamond_suit -> diamonds_(suit)
alias diamond_symbol -> diamonds_(suit)
alias diamonds_suit -> diamonds_(suit)
implicate diamonds_(suit) -> suit_symbol
alias ♠ -> spades_(suit)
alias spade_(suit) -> spades_(suit)
alias spade_suit -> spades_(suit)
alias spades_suit -> spades_(suit)
implicate spades_(suit) -> suit_symbol
implicate hearts_(suit) -> suit_symbol

END of part2

Added in "imply hearts_(suit) -> suit_symbol",
since nothing implies-or-aliases TO hearts_(suit), this should be ok.
