Caio,
You almost have it. Just add a hyphen - immediately before \markup inside
the function and when you call the function in the music with \circled (or
using an underscore _ or carat ^ if a specific direction is needed) and it
should work in both versions (2.18.2 and 2.19.23):
circled = #(define-music-function (parser location txt) (string?)
#{ -\markup { \circle #txt } #})
\relative c' { c-\circled #"1" c_\circled #"dn" c^\circled #"up"}
