Arrows in Labels - Arcade

Question

Is there a way to change the size/bold of just the arrow in my labels? Using arcade to create these based on this Esri article.

Instead of using that character for your arrow, you could use a different character and wrap it in the FNT formatting tag specifying a symbol font. For example, the ESRI Business font includes some bold arrows that could be useful. "a" produces a right-facing arrow "b" produces a left-facing arrow If the character is embedded in your attribute table instead of in the label expression, use the Arcade Replace function to replace the characters → and ← with the above formatting tags.
