IDN: Fix compile time detection of linidn2 TR46 #1207
It depends what you want. If you want TRANSITIONAL, you have to adjust the test. If you want NON-TRANSITIONAL, you are basically at IDNA2008 plus input mapping (NFC, lowercasing, ...).
If you go with that (or similar), I would implement this for wget/wget2 as well.
Well, I want curl to work with IDN on the .de TLD as they require it. Users won't know what option to use for that, so we need to pick one to use. Changing the test case doesn't make us work with that, only changing the code will. Clearly the transitional option is not good enough for that use case. I took out the transitional again in commit ee35766.
I rather wait for someone to actually need an option to modify the IDNA level before we introduce that.
For example... German Umlauts (same goes for accents and special northern europe letters) may be in decomposed form (NFD/NFKD) or composed form (NFC/NFKC). TR46 accepts them both due to internal NFC transforming.
Yes, IDN2_NONTRANSITIONAL has been added with the same version as IDN2_TRANSITIONAL.
