A script to echo emojis

SUMMARY

When printing a sequence of emojis characters some of them are hidden.

STEPS TO REPRODUCE
1. Execute the `echo` script I've attached in the `konsole` terminal. 

OBSERVED RESULT

The first line prints only three emojis and the second line prints the one
hidden in the first line.

EXPECTED RESULT

The first line should print four emojis and the second line should print one
(this is already correct at the moment). I've tested in other terminal apps
(terminator 2.1.2 and vscode terminal 1.75.0) and the first line is printing
the four emojis in the first line.
