Json file to powershell and back to json file

Question

I am trying to manipulate json file data in powershell and write them back to file. Even before the manipulation, when I just read from the file, convert it to a Json object in powershell and write it back to the file, some characters are replaced with some codes. Below is my code:

$jsonFileData = Get-Content $jsonFileLocation

$jsonObject = $jsonFileData | ConvertFrom-Json

... (Modify jsonObject) # Commented out this code to write back the same object

$jsonFileDataToWrite = $jsonObject | ConvertTo-Json

$jsonFileDataToWrite | Out-File $jsonFileLocation

Some characters are replaced by their codes. For example:

< is replaced by \u003c
> is replaced by \u003e. 
' is replaced by \u0027

Input Example:

{
    "$schema": "https://source.com/template.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "accountName": {
            "type": "string",
            "defaultValue": "<sampleAccountName>"
        },
        "accountType": {
            "type": "string",
            "defaultValue": "<sampleAccountType>"
        },
    },
    "variables": {
        "location": "sampleLocation",
        "account": "[parameters('accountName')]",
        "type": "[parameters('accountType')]",
    }
}

Exit:

{
    "$schema": "https://source.com/template.json#",
    "contentVersion": "1.0.0.0",
    "parameters": {
        "accountName": {
            "type": "string",
            "defaultValue": "\u003csampleAccountName\u003e"
        },
        "accountType": {
            "type": "string",
            "defaultValue": "\u003csampleAccountType\u003e"
        },
    },
    "variables": {
        "location": "sampleLocation",
        "account": "[parameters(\u0027accountName\u0027)]",
        "type": "[parameters(\u0027accountType\u0027)]",
    }
}

Why is this happening and what can I do to not replace the characters and write them the same way?
