CB F5 D0 B4 50 43 CA C7 D6 B8 是：
缩写PC是指
其中，中文4个，西文2个

用 VB 判断
Private Sub Command1_Click()
Dim nStr As String, B() As Byte, S As Long, I As Long

nStr = "CB F5 D0 B4 50 43 CA C7 D6 B8" '
ReDim B(1 To 1)
For I = 1 To Len(nStr) - 1 Step 3
S = S + 1: ReDim Preserve B(1 To S)
B(S) = "&H" & Mid(nStr, I, 2)
Next

nStr = StrConv(B, vbUnicode)
I = Len(nStr)
S = (S - I)
MsgBox nStr & "：中文" & S & "个，西文" & I - S & "个", vbInformation
End Sub
