Beyond UTF-8 and Latin1: A Deeper Dive into Character Encodings
Beyond the surface-level differences in character encoding, there lies a fundamental distinction between UTF-8 and Latin1. This disparity stems from their respective purposes and scope.
In the polyglot realm of character encodings, UTF-8 stands as the universal champion, engineered for global character representation. It natively accommodates the full spectrum of characters used in various languages, including complex scripts such as Chinese, Arabic, and Cyrillic.
In stark contrast, Latin1 is a more limited encoding, primarily suitable for languages rooted in the Latin alphabet. Its 8-bit character set assumes that textual data will primarily consist of characters found in English and related languages.
This contrast is particularly evident when dealing with non-Latin characters. For example, storing Chinese characters using Latin1 will inevitably result in mojibake, a garbled representation caused by mismatched character encoding. UTF-8, on the other hand, handles such characters seamlessly, rendering them correctly without corruption.
In the realm of databases, MySQL 5.5 and later versions embrace the full might of UTF-8, introducing the utf8mb4 encoding that supports 4-byte characters. This extends UTF-8's capabilities beyond the Basic Multilingual Plane (BMP) to encompass the Emoji plane and other extended character sets.
The above is the detailed content of UTF-8 vs. Latin-1: Which Character Encoding Should You Choose?. For more information, please follow other related articles on the PHP Chinese website!

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
