Hi everyone, I’ve found some time to continue breaking WordUtils into separate classes (eschewing the “big collection of static methods” approach). However, as I read more about case handling in Unicode, I realise how simplistic the WordUtils methods are and how complex a full solution would need to be.
Section 5.18 of the Unicode specification [1] describes these complexities. The mains ones that bother me are: 1. Title case conversions vary widely between different locales and languages. I’m not clear whether any locale is satisfied by the current simplistic implementation in WordUtils.capitalize(str). Supporting this correctly would be a serious challenge. 2. All types of case conversion may vary depending upon context/locale. There are examples provided in [1] where the outcome is different in a Turkish locale or if the letter in question is followed by another or not. Does anyone have a suggestion for how to move forward with this work? I see three options: 1] Admit defeat and avoid the case conversion mess entirely. 2] Mimic the existing functionality, but document the limitations. 3] Attempt to deliver a locale-dependent version, perhaps still with limitations (or for certain languages). I’m leaning towards 2, perhaps even calling the classes “SimpleX…”.
