  The processing of Unicode text is among the most foundational operations in modern computing, yet the algorithms that govern it—segmentation, normalization, bidirectional layout, collation—are specified across more than a dozen Unicode Technical Annexes and Reports, each encoding rules of considerable complexity. Implementations of these algorithms in widely used libraries have historically been written in memory-unsafe languages without formal guarantees, relying on testing alone to establish correctness. The question of whether a Unicode text processing library can be not merely tested but proved correct—with machine-checked guarantees of both the absence of runtime errors and functional conformance to the Unicode Standard—has not, to the authors' knowledge, been addressed prior to this work.
