Power query sorting is different from the Excel sorting

[Lolo]

Hello,

I'm facing with an annoying issue with power query sorting action.
Seems Power query sorting manage differently the special chars than Exel in the sort.

LEt me explain with a basic example :
I have a table with the basic following values, unsorted

Col1
val1
¨val1
_val1

If in Excel I sort ascending the table by Col1, result is :
Col1
_val1
¨val1
val1

and it is the result I expect.

If these data are now in power query, I execute the sort in power query with Table.Sort instruction and load data to workbook
the result is now :
Col1
_val1
val1
¨val1

You can find attached the workbook

So the Excel sorting is different from the Powerquery sorting, which cause some issues for me

Any idea on how I can use power query and having the excel sorting behavior ?
The single workaround found is to create a macro that refresh power query table, and after sort the result in excel

Thank you for your help.
