I would like to congratulate Ergonis software, which is now celebrating 30 years of the Mac utility PopChar. Keeping a software application running for 30 years is quite an accomplishment. PopChar allows you to easily see all of the characters attached to your various fonts. There's a lot in there, and if you're looking for a specific symbol or emoji, they aren't always that easy to find. PopChar solves that problem—and has been solving that problem for 30 years now.
If the character lists Apple provides you with when you hold down Control + Command + Space isn’t solving the problem for you, you should check out PopChar. Best of all, with the 30-year celebration, it's reduced by 45% until May 24 ($16.50 for an individual license.) Follow this link to get the discount coupon code "PopChar30”.
