Topics: strings, text-processing, unicode, utf-8

Classification scope and review notes

UTF-8 string handling using one array element per encoded Unicode code point. The main verifies a round trip, code point count, substring, search and replacement of accented text, and prints the results. No source edits. Combining marks remain separate code points; grapheme segmentation, normalization and malformed-input handling are not validated.
