研究方向
Investigate the existing utf8 fast paths in Node.js's fs module (likely in lib/internal/fs/utils.js or src/node file.cc). Examine issues #48658 and #49884 for context. Determine where UTF8 and UTF 8 strings are compared and make the comparison case insensitive or add the accepted variants. Ensure consistency with the encoding normalization function. Add tests for the new accepted values.
