This library is a header-only C++ framework that performs regular expression evaluation and static string analysis during the compilation phase. By leveraging template metaprogramming and constant expression evaluation, it transforms pattern matching logic into static state machines, effectively shifting the cost of parsing and validation from runtime to build time. The project distinguishes itself by encoding text data directly into the type system, allowing for the validation and extraction of string content before a program ever executes. This approach ensures that regular expression patte

ICU is a C++ and C internationalization software library implementing global Unicode standards for multi-language text processing, collation, and locale-aware data formatting. It functions as a text processing toolkit for transforming, searching, and normalizing character strings across various scripts and language encodings, while handling character sets according to the Unicode Character Database. Operating system differences are hidden behind a consistent internal hardware layer that handles memory allocation and character encoding uniformly. The system passes strings through canonical de
