There are some very important characters that cannot be used in article titles, like quotation marks, currency signs (in my case, dollar signs), and percentages. I can think of myriad ways to title articles with the above symbols, like: – Troubleshoot "Installation Failed" Error – Manage Software Licenses above $100 – How to Reach Success Rates over 90% Currently, hashtags and the @ symbol are possible for titles, so why not ", $, or %? Thank you! :)
