Now let’s delve into another important encoding scheme known as UTF-8 without any transitional phrases or explicit mention of “steps”.


Character Encoding and Thai Keyboard Support

ASCII (American Standard Code for Information Interchange) is a widely used character encoding standard that represents text in computers. However, ASCII has limitations when it comes to supporting non-English languages like Thai. To overcome this limitation, another character encoding standard called UTF-8 (Unicode Transformation Format – 8-bit) was developed.

Let’s consider an example of someone typing a document in Thai using a keyboard that follows the ASCII character set. When they try to type Thai characters, such as “สวัสดี” which means “hello,” the keyboard may not recognize these characters since they are outside the range defined by ASCII. As a result, the typed text might appear as gibberish or incorrect symbols on the screen.

To address this issue, UTF-8 was introduced. It is designed to support multiple languages and can represent virtually any character from any writing system in existence today. Here are some key points about UTF-8:

  • Universal compatibility: UTF-8 is backward compatible with ASCII, meaning that all ASCII-encoded documents are also valid UTF-8 encoded documents.
