Add-PnPListItem fails whwn & sign in the managed metadata field data (PowerShell)

Question

I have a list with managed metada column (column name - Proficiency).

I am creating the new record in my list with the following PnP command:

Add-PnPListItem -List "Skill Matrix" -Values @{"PersonnelNumber" = 343; "Skill" = $skill; "Proficiency" = "P0 - No Skills"}

It works perfectly when there is no special character (&) in the skills but it fails for the following Skills because of & sign:

$skill = "SAP Skills|HANA Technical|Basis|Installation & Operations"

I tried to replace it with & but still it didn;t work.

Anyone please suggest me how to implement this.

Thanks.

Answer 1

This is an issue with unicode character and something to do with SharePoint not understanding & character, especially the Taxonomy APIs.

What you can do is to replace & with ＆ in your taxonomy label value in your script and it should work. They both look almost the same but are actually different.

You can check a reference here :- Setting managed metadata fields using PnP PowerShell

Answer 2

As I test,@Gautam's way works well. And there is another way to insert metadata.You could insert metadata value with term id,this way could avoid the influence of special symbols.
