Has anybody written a wrapper around `std.file.readText` (or similar) that appends a final zero-byte terminator in order to realize sentinel-based search in textual parsers.

What do you mean by similar? There are many ways to load a file into memory before appending \0. In fast.json I used a memory mapped file. On some OSs you can read past the end of such mappings safely to generate extra \0 bytes. 16 zero-bytes is a good amount if you want to use the SSE4.2 string instruction.
