Ah! Most likely the pull request "Adding support of UTF8 file name processing in mio on windows" (https://github.com/mandreyel/mio/pull/64) of shivendra14 will solve this issue as a side effect.

I am having several issues getting the patch to work: a) I am missing an `#include `. and when I fix this I get b) 'std::wstring mio::detail::win::s2ws(const std::string &)': cannot...

Unfortunatly, I still have two issues with the your last commit https://github.com/mandreyel/mio/commit/3f86a95c0784d73ce6815237ec33ed25f233b643 Issue a) Error C2039: `'vector': is not a member of 'std'` in line 802 of mio.hpp Which means,...

**Off Topic**: The warnings, my compiler throws are (after applying the patch above): ``` ...\mio.hpp(885,39): warning C4244: 'return': conversion from 'int64_t' to 'size_t', possible loss of data ...\mio.hpp(910,61): warning C4244:...

Hello, I just stumbled across this little essay and thought it fit the topic: https://blogs.msmvps.com/gdicanio/2021/03/26/the-case-of-string_view-and-the-magic-string/

As I (not native speaker) understand it, 'cast' denotes a operation, so 'cast_to' sounds more correct than 'cast_in', which might better mean 'casted_in'. Are 'stored_in', 'kept_in' or 'hold_in' alternatives?

Ah ok, thanks for clarification. So, 'unsafe_cast_to' is a little bit too unhandy? 'forced_to' does not pose any risk of confusion for me. PS: You mean '[coerce_in](https://aurora-opensource.github.io/au/main/reference/quantity/#coerce)'
