A dot is treated differently if it has a number on no, one, or both sides.

[,1]
[1,] "me.com"

[,1] [,2]
[1,] "me1" "com"

[,1]
[1,] "me1.2com"
?stri_extract_all_words
sent me to
?"stringi-search-boundaries"
which suggests that you should spend some time with the user guide:
_Boundary Analysis_ - ICU User Guide, <URL:

Depending on your objective, you might be better off with strsplit()
separating on whitespace.
