Ranges has made a precedent that we can provide better versions of old functions by putting them into a separate namespace. It is general consensus that almost all current text related function are obsolete. We should consider a namespace for new ones. I think std::text fits this. This namespace would contain functions that are modern and can properly support Unicode (and other encodings!). There is also a precedent of my proposal and D1628 having separate namespace specifically for Unicode. Generally speaking, Unicode is a subset of text processing so in mathematical sense it would be obvious to put unicode namespace as std::text::unicode but here I agree that it is too much typing. So I propose the following: std::text for general purpose text algorithms (to be determined as we haven't even nailed the Unicode yet, but consider std::text::to_upper, std::text::is_alphanumeric). std::unicode for Unicode classes and algorithms. Everything in std::text should be able to work with classes from std::unicode. Then we can add more encodings under std or maybe right into std::text if they are too simple. Theoretical examples: std::ascii std::ebcdic std::shift_jis
