That’s what Google does for Android, because OraSun’s doesn’t measure up. The easiest way to get a standards-comforming regex library for Java is to JNI over to ICU’s stuff. Yes, it’s possible, and yes, it’s a mindnumbing mess. Java’s regexes just don’t work very well on its own native character set, and so you really have to jump through exotic hoops to make them work.Īnd if you think white space is bad, you should see what you have to do to get \w and \b to finally behave properly! Now you can use whitespace_charclass + "+" as the pattern in your replaceAll. * A \S that actually works for Java’s native character set: Unicode */ * A \s that actually works for Java’s native character set: Unicode */ Even so, Java has no property that conforms to The Unicode Standard for these, so you instead have to use code like this: String whitespace_chars = "" /* dummy empty string for homogeneity */ White space is a pretty stable property, and those same ones have been around virtually forever. ![]() Unicode defines 26 code points as \p GeneralCategory=Control. You can’t use \s in Java to match white space on its own native character set, because Java doesn’t support the Unicode white space property - even though doing so is strictly required to meet UTS#18’s RL1.2! What it does have is not standards-conforming, alas.
