Is it a Unicode Font?

To determine if your font is Unicode-compliant, with all its characters coded and mapped correctly, choose the Font in any program (or in Font Book, set the preview area to Custom (Preview > Custom), and type Option-Shift-2.

If you get a euro character (a sort of uppercase C with two horizontal lines through its midsection), it's 99.9 percent certain the font is Unicode-compliant. If you get a graphic character that's gray rounded-rectangle frame with a euro character inside it, the font is definitely not Unicode-compliant. (The fact that the image has a euro sign in it is only coincidental: it's the image used for any missing currency sign.)

This assumes that you're using U.S. input keyboard, which is a little ironic when the euro symbol is the test. With the British keyboard, for instance, Option-2 produces the euro symbol if it's part of the font.

Fascinating Speed Comparison across All iPhone Models

Send Article to a Friend

There’s no question that the A7 chip in the iPhone 5s is the fastest processor ever to grace an iPhone, but how does the performance it provides compare with that enjoyed by previous generations of the iPhone? In this fascinating YouTube video, user EverythingApplePro lines up eight iPhone models and shows how they compare at powering up and down, and loading several Web sites.favicon follow link

That is a great video. Thanks for taking the time to make it! Your conclusion is spot on.

I shared this with a tech friend who made an interesting observation:

"He also (perhaps unwittingly) hits on a truth about modern hardware that is the chip making industry is really struggling now to find new ways to keep improving processing speed. We’re seeing a flattening of the progress curve as each generation slows down the speed of progress relative to the previous generation. Chipmakers can’t keep doubling speeds every 12-18 months like they did a decade ago."

I think it's more subtle than that. More CPU power is always good, but once you hit a certain point, it can't make a difference for many tasks - viewing a Web page is a perfect example. You don't want it to be slow, but adding CPU power will stop helping at some point since that's just not a bottleneck.

Instead, companies have to put the CPU power to use in new and innovative ways, such as by tracking usage to predict behavior and make it better, for instance. That's something that wasn't possible in the past because the CPUs were busy handling just basic tasks.
