Using a Text to ASCII Converter in Cross-browser Testing
A text to ASCII converter can be useful if you're doing cross-browser testing. For example, if you're making a web application that can't accept Unicode as input (for example, email field or age), then a quick test to check that the input text isn't Unicode is to convert it to ASCII codes, and check that all code point values are less than 255. If there's a code value larger than 255, then there's a Unicode character in the input. Several other use cases for an ASCII code converter are hiding spoilers in forums so that people first have to decode the code values to read the answer and debugging input data by checking the numeric values of characters.
