What do you understand by "storage"?

To have string stored as UTF-8 only, no conversion required for 99% of our use.


I think that the first thing that needs to be agreed on is if there will be support for UTF-8 in the core? As has already been said, in many places this currently just works and so blocking that may be more of a problem now? The question surly is "What is the 1% that needs some extra work?"

I light library would be most appropriate for filling the gaps currently created by use of UTF-8 strings in the core? It is not until one starts adding the mbstring level of string processing that a more powerful library is required. Something that simply ensures UTF-8 strings are valid and can carry out comparisons as required?

The black hole is still 'case sensitivity' and it is perhaps laying down a 'light' set of rules for this which would allow a path forward? As I have indicated, I'd prefer simply dropping case insensitivity, but a compromise might be to retain it where a string length does not change, and a clean reverse transform exists? So a library that provides that comparison as part of the core package?

I think that moving forward, ICU support is essential, but it is difficult while the 'wrong' defaults are applied and I am seeing private builds being used in other projects to get around that hurdle. Hence my question as to if people are taking that approach.
