VBA宏替换问题：如何用ChrW(&H2713)勾选符号替代字母L？

我找到一个可在指定范围内将字母替换为某一字母、数字替换为另一字母的VBA宏，代码如下：

Public Const Letters                As String = "abcdefghijklmnopqrstuvwxyz"
Public Const Numbers                As String = "0123456789"
Public Const FoundLetter            As String = "L"
Public Const FoundNumber            As String = "N"

该宏运行正常，但我希望用勾选符号（ChrW(&H2713)）替代字母L，请问应将As String = "L"改写为哪一行代码？

将原来的Public Const FoundLetter As String = "L"替换为：

Public Const FoundLetter            As String = ChrW(&H2713)
