> I mean title in the sense of the name of a work or entity. "Henry the 8th" or "Henry the 8." conveys exactly the same information as "Henry VIII". The context makes it clear that the numeral is part of a designation. The same is true for "Star Wars Episode 4", "Act 2 Scene 5", "Harry Potter 2" or any other use of a title. The difference is: 8 is trivially easy to parse. With "VIII", software has to accomodate people writing it in unicode and people writing it in latin letters, plus the parser needs to handle the subtraction logic, otherwise "Henry IV" will be sad, and as a human, depending on the font used, I may have to look twice whether there are 2 I's or 3. > This is strictly harder to parse. What? How is this harder to parse? The dot after the numbers makes it increadibly clear that this is a list item. You know what CAN be hard to parse at a glance? The difference between "III" and "II". > roman numerals allows you to further capitalize a number. No they don't because there is no such thing as a "capitalized number". If I want to make a number stand out visually, I have multiple choices that don't require using an antique way of writing numerals: I can use <b>, <u>, <i>, change the font, font size or even color my numbers. > This makes it clearer that the II is part of the name. "Doom 2 ships on 4 floppy disks" is just as clear. As with the examples above, the context determines what is part of a title, and what isn't.
