JSON messages going to LS have URIs with non-ASCII chars

[BoykoAlex]

A URI to a file named: ClassWithSpécialCharacter.java (note non-ASCII é in the name) in its string form in the JSON still looks the same without é escaped. VSCode LSP client sends this url with file name that looks like: ClassWithSp%C3%A9cialCharacter.java which is correct. URIs with unicode chars are illegal... The issue I have faced is Paths(URI.create(uriStr)) throws java.lang.IllegalArgumentException: Bad escape

Test project with such file: https://github.com/spring-projects/sts4/tree/main/headless-services/spring-boot-language-server/src/test/resources/test-projects/test-annotation-indexing-parent/test-annotation-indexing%20with%20space

Should be fixed now. Will see if lsp4j will have anything in addition via eclipse-lsp4j/lsp4j#692
