Salesforce Fact #577 | apex:outputText formatting
apex:outputText supports value formatting using apex:param tag. Reference: https://developer.salesforce.com/docs/atlas.en-us.pages.meta/pages/pages_compref_outputText.htm Attached is the screenshot. Note: the <apex:outputText> component doesn't respect the View Encrypted Data Permission for users. To prevent showing sensitive information to unauthorized users, use the <apex:outputField> tag instead.
