Welcome to SO! Can you update your question with some more information what error you are exactly getting? :) — Tom, Jun 15 '19 at 07:56
Use the mid command to replace the blue heart :- mid(tStr,3,1)="" — BASit Bulbulia, Jun 15 '19 at 09:15
`tStr = tStr.Replace("", "")`. This question is getting too emotional. — Jimi, Jun 15 '19 at 22:15

The index number used by the Remove and Insert methods are zero-based (the index of the first character is 0). To get the third emoji, you need to use 4 as the index instead of 5.

dim tStr as String =""
tStr=tStr.Remove(4, 2)
tStr= tStr.Insert(4,"")
