catch3/src/catch2/internal/catch_string_manip.cpp, branch 0.2.0 Progmasoft Catch3: an independently maintained C++17 test framework with a parallel runner, property checks, snapshots and structured results. Use locale-independent toLower 2026-09-11T09:15:58+00:00 Martin Hořeňovský 2026-09-06T21:23:23+00:00 6a5075bf73273ecb83fca61efdfde2fa1a2690bf We generally do not even try to pretend to support more than plain ASCII, because doing unicode in old C++ standards is a pain and a half. For `toLower`, we used to wrap `std::tolower` with multiple casts to avoid UB, but calling into it is relatively slow, and it tries to handle different locales, which could cause unexpected results. In addition, the new implementation is significantly faster, which helps speed up the initial process bring up (as comparing tags, and thus test cases is now faster).

This means that it can no longer be safely made ahead of time,
but nothing in our existing code used it like that. Normally it
is constructed and used in the same expression, which is now
more efficient.

This should also be done for test files, but that has lower priority.
