Julia returns: julia> c='ı' 'ı': Unicode U+0131 (category Ll: Letter, lowercase) julia> uppercase(c) 'I': ASCII/Unicode U+0049 (category Lu: Letter, uppercase) julia> lowercase(uppercase(c)) 'i': ASCII/Unicode U+0069 (category Ll: Letter, lowercase) Is this something that needs changing in the Unicode spec itself or how strings are handled in general by various tools/programming languages? I love [plain] text, but it's so, so fragile. :/
