function Get-DbaLocaleSetting {
<#
    .SYNOPSIS
        Gets the Locale settings on a computer.
 
    .DESCRIPTION
        Gets the Locale settings on one or more computers.
 
        Requires Local Admin rights on destination computer(s).
 
    .PARAMETER ComputerName
        The target SQL Server instance or instances.
 
    .PARAMETER Credential
        Credential object used to connect to the computer as a different user.
 
    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
