Help converting regex (to remove emojis)

There are many issues here. Both characters above are not in the range you specified in the first place.

ā–¶ to_charlist "šŸ’°" 
#ā‡’ [128176]
ā–¶ to_charlist "šŸ’²"
#ā‡’ [128178]
ā–¶ 0x1F600
#ā‡’ 128512

To make it work for the range with \u, just interpolate the literals (I voluntarily changed the starting value for the range to what it probably should be):

ā–¶ Regex.replace(~r/[#{"\u{1F000}"}-#{"\u{1F6FF}"}]/u, "šŸ’° Monies! šŸ’²", "")
" Monies! "

\x will work out of the box with a proper range:

Regex.replace(~r/[\x{1F000}-\x{1F6FF}]/u, "šŸ’° Monies! šŸ’²", "")
" Monies! "
