Code​:
say gather â��abcâ�� ~~ m​:g/ . {take â��Xâ��} /

Result​:
(X)

I expected to get three X-s, but I only got the first one (like if it lost :g).

However, if you just ï½¢sayï½£ it, then you get the right result​:
â��abcâ�� ~~ m​:g/ . {say â��Xâ��} /

Result​:
X
X
X

Same problem with exhaustive​:
say gather â��abcâ�� ~~ m​:ex/ .+? {take â��Xâ��} /

Result​:
(X)

Interestingly, backtracking works as expected​:
say gather �bc� ~~ m/(.)* {take �X�} �c� /

Result​:
(X X)
