builtin/repo: fix table alignment for UTF-8 characters

2025-11-17T00:04:24Z

The output table from "git repo structure" is misaligned when displaying UTF-8 characters (e.g., non-ASCII glyphs). E.g.: | 仓库结构 | 值 | | -------------- | ---- | | * 引用 | | | * 计数 | 67 | The previous implementation used simple width formatting with printf() which didn't properly handle multi-byte UTF-8 characters, causing misaligned table columns when displaying repository structure information. This change modifies the stats_table_print_structure function to use strbuf_utf8_align() instead of basic printf width specifiers. This ensures proper column alignment regardless of the character encoding of the content being displayed. Also add test cases for strbuf_utf8_align(), a function newly introduced in "builtin/repo.c".

t/unit-tests: add UTF-8 width tests for CJK chars

2025-11-17T00:04:24Z

The file "builtin/repo.c" uses utf8_strwidth() to calculate the display width of UTF-8 characters in a table, but the resulting output is still misaligned. Add test cases for both utf8_strwidth and utf8_strnwidth to verify that they correctly compute the display width for UTF-8 characters. Also updated the build configuration in Makefile and meson.build to include the new test suite in the build process. Signed-off-by: Jiang Xin Signed-off-by: Junio C Hamano
