From 4c835f0337674a0181c43f448d44d961e27b2f54 Mon Sep 17 00:00:00 2001 From: Sven Gothel Date: Thu, 28 Nov 2013 12:47:46 +0100 Subject: IOUtil.toURL(..) Apply decodeFromURI(uri.getPath()) if file-scheme; Add IOUtil.decodeURIToFilePath(..) for native usage. Refine comments, API doc. toURL(..): Apply space conversion, decodeFromURI(..), on file-scheme path, ensuring decoded space. ++ Add decodeURIToFilePath(String uriPath) and decodeURIToFilePath(URI uri) Both methods shall simplify decoding a file-URI for native platform usage.
