This is actually no long possible. It was a really popular thing back early and pre-aos with runebooks, guildstone (names) and houses. Back then you could utilize HTML code, which required "<>" which are now changed to "()" when used to name items like house signs, runebooks, guilds etc.
However things that had already been named were grandfathered into the game, thus if you already have items named like that, unless you rename them, they will retain the name. This was a change made because it was a means to scamming people with runebooks, altering their names to be something completely different. For example I made a couple runebooks that were called "a spellbook" and sold them for about 20m each a long time ago.
