Power automate sending damage pdf files due to encoding using an array variable to insert attachment in the mail

[Tom_FR]

Hello everybody,

I'm having trouble to send a pdf file (from sharepoint) as an attachment to an e-mail.
I'm using an array variable to let a Powerapp user choose which pdf he wants to send thanks to a boolean test.

The flow itself works fine but the pdf files inserted in the mail are damaged.
find out that the encoding was in UTF-8 for the damage file. the original file is encoded in ANSI.

there is the same kind of problem here : https://sharepoint.stackexchange.com/questions/265736/flow-sending-mail-attachment-with-bad-encoding

They solved it by not using variables, theythink it's the variable that encode in UTF8 and damage de the file.
But for the sake of my conditional flow i need to use an array variable to be able to attachment different 0 or 1 or 2 or 3 or 4 files to my mail.

correct me if I'm wrong but : In other words, i need to use an array variable that will not encode my file in UTF-8

do you have any idea of how to solve that problem ?

Thank you for your attention,

Tom
