You could use a userdefined function to extract the bold characters:
Option Explicit
Function GetBoldChars(myCell As Range) As String
Application.Volatile True
Dim iCtr As Long
Dim OutStr As String
Set myCell = myCell.Cells(1) 'one cell at a time
OutStr = ""
If myCell.Font.Bold = True Then
OutStr = myCell.Value
Else
If myCell.Font.Bold = False Then
OutStr = ""
Else
For iCtr = 1 To Len(myCell.Value)
If myCell.Characters(Start:=iCtr, Length:=1).Font.Bold _
= True Then
OutStr = OutStr & Mid(myCell.Value, iCtr, 1)
End If
Next iCtr
End If
End If
GetBoldChars = OutStr
End Function
Be aware that if you change the formatting of the cell, then this formula cell
won't change until your workbook calculates.
If you're new to macros, you may want to read David McRitchie's intro at:

Short course:
Open your workbook.
Hit alt-f11 to get to the VBE (where macros/UDF's live)
hit ctrl-R to view the project explorer
Find your workbook.
should look like: VBAProject (yourfilename.xls)
right click on the project name
Insert, then Module
You should see the code window pop up on the right hand side
Paste the code in there.
Now go back to excel.
Into a test cell and type:
=GetBoldChars(a1)
