ID: 65132 Updated by: ahar...@php.net Reported by: daniel at 203core dot se Summary: trim does not include non breaking whitespace -Status: Open +Status: Wont fix Type: Bug -Package: Scripting Engine problem +Package: Strings related Operating System: FreeBSD 9.1 PHP Version: 5.4.16 Block user comment: N Private report: N New Comment: There are multibyte encodings which are ASCII compatible where a0 is a valid byte in non-space characters, Shift JIS being the most obvious one. There would also be the issue that a0 is only part of the non-breaking space character in UTF-8 â to trim UTF-8 NBSPs, you'd have to also include c2, which would cause even more problems. As a result, we can't really change this. Closing won't fix.
