Portable UTF-8
A portable, performance-optimized UTF-8 string library for PHP that works without mbstring or iconv extensions.
What is Portable UTF-8?
Portable UTF-8 is a comprehensive PHP library that provides Unicode-aware string functions, ensuring reliable UTF-8 handling across different server environments. It solves the problem of inconsistent UTF-8 support by offering a full suite of string operations (like strlen, strtoupper, substr) that work properly with multi-byte characters, even when common PHP extensions like mbstring or iconv are unavailable. This makes PHP applications more portable and robust by guaranteeing consistent string behavior regardless of server configuration.
PHP developers building applications that need to run reliably across diverse hosting environments, especially those where server extensions cannot be guaranteed or controlled. It's particularly valuable for open-source project maintainers, shared hosting users, and developers working with internationalized content requiring proper Unicode handling.
Developers choose Portable UTF-8 because it provides guaranteed UTF-8 support without extension dependencies, using pure PHP fallbacks when needed. Its unique selling point is automatic performance optimization—it detects and uses available PHP extensions (mbstring, iconv, intl) for maximum speed when present, while maintaining full functionality through polyfills when they're absent, offering the best of both portability and performance.
