If you find yourself regularly needing to find and enter special characters in different fonts, that task has now become easier in Mac OS X 10.7 Lion, with Ergonis Software’s release of PopChar X 5.3. The new release supports colored symbols in the new Apple Color Emoji font; these can now be browsed and searched for, and inserted as characters in applications that know how to handle color fonts. Some additional tweaks, such as reduced CPU load in the background and better compatibility with Lion’s desktop spaces, round out the update. (€29.99 new, free update, 2.3 MB, release notes)
Enabling Auto Spelling Correction in Snow Leopard
In Snow Leopard, the automatic spelling correction in applications is not usually activated by default. To turn it on, make sure the cursor's insertion point is somewhere where text can be entered, and either choose Edit > Spelling and Grammar > Correct Spelling Automatically or, if the Edit menu's submenu doesn't have what you need, Control-click where you're typing and choose Spelling and Grammar > Correct Spelling Automatically from the contextual menu that appears. The latter approach is particularly likely to be necessary in Safari and other WebKit-based applications, like Mailplane.
