The first commercially-available computers could only display or accept English. That was a problem. By the time I first started using computers, we had a few more characters available because of something called “extended ASCII”. This allowed the computer to display and accept keyboard input for most European languages. But it still didn’t work all that well. Specialized technicians had to fiddle with the computer to get it to accept and display the characters in the alphabets of African languages we were working on, But every language had its own system, making archiving and computer support a mess.

Technical details for unicode for one specific language
Fortunately, the tech companies wanted to sell their products everywhere, so they were interested in solving this problem. Missionary-linguists got involved in a worldwide consortium working on the issue. We jumped in so that the smaller languages wouldn’t be left out. Besides, we were often the only ones who had thought about what they needed. In the end, we got unicode; a world-wide standard for accepting, displaying and printing all the characters of all the languages of the world, even Tai Lue, wherever that is.
Your smart phone has unicode, your computer has it, your TV has it, maybe even your car and your refrigerator. Someday your doorbell might have it. Actually, I think some already do. You use missionary technology every day. So do atheists.
Now, anyone who wants to read the Bible in his language, no matter how strangely it is written, can see it displayed on a smart phone, tablet or computer. Because of unicode, the Bible in any language can be sent across the internet or put on small chips and carried anywhere. Whatever electronic device receives it will display the strangest characters correctly. Unicode, hidden the background, makes it happen automatically.
