Modify Powershell Script to remove asterisk from HTML file

I would like to modify this Powershell script to remove an asterisk which is appearing in the html file.

The current error I am getting is:

The regular expression pattern * is not valid.
At C:\Users\User1\Desktop\Report.ps1:39 char:1
+ ((Get-Content -path $writeto -Raw) -replace $oldcontent,$newcontent) ...

$oldcontent = '*'
$newcontent = '<span style="color: rgb(51, 102, 255); font-weight: bold;"'
$writeto = 'C:\Users\User1\Desktop\Report.html'

((Get-Content -path $writeto -Raw) -replace $oldcontent,$newcontent) | Set-Content -Path $writeto

Open in new window

An asterisk is a special character in a regular expression.
You need to escape it:

$oldcontent = '`*' 
$newcontent = '<span style="color: rgb(51, 102, 255); font-weight: bold;"' 
$writeto = 'C:\Users\User1\Desktop\Report.html' ((Get-Content -path $writeto -Raw) -replace $oldcontent,$newcontent) | Set-Content -Path $writeto

It's a backwards apostrophe/grave (the character under the tilde).
