Using a Character Counter in Cross-browser Testing
A character counter can be useful if you're doing cross-browser testing. For example, if your web application supports multiple languages, then the letter statistics can be used to determine which language the given text is written in. With this utility, you can create various test cases that check and determine the language of the given text. In the English language, the character "e" appears most often, then the characters "o", "a", and "t". In the French language, it's the characters "e", "s", "a", "i", and in other languages this distribution is different. To write such a test case, the input would be text, and the output would be a dictionary of letters and their counts. Additionally, you can use this utility to just analyze letters in your own text or a document.
