How to pseudo-translate, Part I

Before you localize your software product, wouldn't you like to have an idea of what's going to break as a result?

If you've written it in English, it will surprise and alarm you to learn that that's no assurance that it will work when the user interface (UI) is in Chinese or Arabic or maybe even Spanish. The most conspicuous vulnerabilities are:

• text swell, in which "prompt" becomes "Eingabeausforderung" in German, for example, and the 40 pixels of width you've reserved in the English UI results in only a small part of the German appearing;
• corrupted characters, which will show up in the UI as question marks or little black boxes because characters such as à, ü, ¿, ß, Ø and 日本語 aren't in the code page or encoding under which your software is compiled;
• illegible or invalid names of files and paths, which occur when installing your software on an operating system that will handle more kinds of characters than your product will;
  
• crashes, which occur when your software mishandles the strange characters so badly that the program just giggles briefly and then dies;
• ethnocentric business logic, which leads to ridiculous results when users select unanticipated countries or currencies;
  
• hard-coded anything, whether currency symbols, standards of measurement (metric vs. English) or UI strings.

In the past, localization efforts have become stranded on these beaches late in the voyage, after the text has been translated and the binaries rebuilt. It needn't be that way.

Internationalization testing is the process of pushing alien characters and situations down your software's throat to see what breaks. The more complex the software, the more complex the testing, such that there are companies that specialize in internationalization as much as if not more than localization.

It's not rocket science, but it doesn't happen on its own, either. And, you don't want your customers worldwide doing any more of your internationalization testing than absolutely necessary, because they really don't appreciate buying the product and then testing it.

The process requires some cooperation between Engineering and QA, which should already be in place for the domestic product and can easily be extended to the international products as well. An upcoming post will explain some of the tools and techniques for proper internationalization testing.
