Box Layout Icon

Appian supports Unicode characters, so you could do this too:

a!boxLayout(

 label: "↕ Monthly Opening And Closing Accounts",

 style: "ACCENT"

)

To further Carlos' solution, you can also use the char() function to render Unicode characters.  That particular up/down arrow is '8579'.  

a!boxLayout(
  label: char(8597) &" Monthly Opening And Closing Accounts",
  style: "ACCENT"
)

I often use this site to find Unicode values: http://xahlee.info/comp/unicode_arrows.html

Yeah, it's working.. Thank you

How compatible are unicode characters w.r.t mobile browsers, mobile apps, different browsers on different systems ?

In my experience, compatibility is fairly high these days, approaching 100% but not necessarily always 100% (and it can also depend on the particular unicode character in question).

You have to watch out for the emoji set, because a lot of those, not all, are rendering in full color on Chrome. I don't know how it will look in a component label like that.
