character set mapping in ilib

character set mapping in ilib: a comprehensive tutorial

character set mapping, also known as character encoding conversion, is the process of translating text represented in one character encoding (e.g., utf-8, iso-8859-1) to another. this is crucial for ensuring text is correctly displayed and processed across different systems and applications that might use different encodings. the `ilib` (internationalization library) provides robust functionality for character set mapping, allowing you to handle various encodings effectively.

this tutorial will provide a deep dive into character set mapping with `ilib`, covering its purpose, common character sets, the `ilib` api for character set conversion, and practical code examples.

**1. understanding character sets and encodings**

before diving into `ilib`, let's clarify the concepts of character sets and character encodings:

* **character set (charset):** a collection of characters and symbols. it's essentially a dictionary that defines what characters are available. examples: ascii, latin-1 (iso-8859-1), cyrillic (iso-8859-5), chinese simplified (gb2312), and unicode.

* **character encoding:** a scheme for representing characters from a character set as numerical values (code points) that computers can understand and process. the encoding defines how a character in a character set is stored in memory as a sequence of bytes. examples: utf-8, utf-16, ascii, iso-8859-1, gbk.

**key differences:**

* a character set is an abstract definition of characters, while a character encoding is a concrete implementation for representing those characters as bytes.
* multiple encodings can exist for the same character set. for example, unicode has encodings like utf-8, utf-16, and utf-32.

**common character encodings:**

here are some common character encodings you'll encounter:

* **ascii (american standard code for information interchange):** a 7-bit encoding representing 128 characters, primarily english lette ...
