--- Comment #4 from Peter VARGA <office at faf dot software> --- I consider "printf" still as the most powerful function. Please, tell me, how do I set in std::format the ' character as thousand separator, which I can do with the localization in printf. So, the output for %'09u should be 000'073'259. A way to achieve it with std::format()?
