You could also use a macro to find out the ascii or asciiWide values to avoid having to use other websites to convert between hex and decimal
Code:
Sub WhatChar()
Dim aChar As Range, sReport As String
sReport = "Char" & vbTab & "Asc" & vbTab & "AscW" & vbCr
For Each aChar In Selection.Range.Characters
sReport = sReport & aChar & vbTab & Asc(aChar) & vbTab & AscW(aChar) & vbCr
Next aChar
MsgBox sReport, vbOKOnly, "Selected characters"
End Sub
Sub InsertUnicodeChar()
Selection.Range.InsertAfter ChrW(8203)
End Sub
