Hello, During a discussion about the deprecation of String.toLowerCase(), String.toUpperCase [1], it occurred to me that the current Note in the API documentation could be more specific when talking about locales.
Before going ahead and suggesting a PR/CSR, I'd like to socialize the idea that we could improve the Notes in these somewhat suspicious methods. The current notes look like this: Note: This method is locale sensitive, and may produce unexpected > results if used for strings that are intended to be interpreted locale > independently. Sensitive to which locale? Independently of which locale? It then goes on to say: To obtain correct results for locale insensitive strings, use > toUpperCase(Locale.ROOT) What are "locale insensitive strings"? Here is an attempt to be more specific: Note: This method is sensitive to the default locale for this instance > of the Java Virtual Machine. It may produce unexpected > results if used for strings that are intended to be interpreted > independent of the default locale. For the last part, I suggest using "language/country neutral results" instead of "locale insensitive strings": To obtain language/country neutral results, use toLowerCase(Locale.ROOT) Any thoughts? Thanks, Eirik. [1] https://github.com/openjdk/jdk/pull/13434#issuecomment-1505832883
