Native English speakers write "hahaha" or "ha-ha-ha", but speakers of many Slavic languages write "ahahaha" or "a-ha-ha-ha", with leading "a".
Native English speakers write ":)", but speakers of many Slavic languages write just ")", because ":" is reused on keyboard for additional Cyrillic letters (like Ж) and they don't use it even when typing in English.
Georgians reuse not only ":დ" as ":D", but basically any English acronym "ლოლ" for lol, "ლმაო" for "lmao", because standard Georgian layout is based on English US layout and it feels natural. Exception is ROFL, because Georgian lacks "F" sound.
