unicode-escapes

In a Scala String need to include this literal verbatim: \usepackage{x} . Thus, desired would be that for val s = """ ... \usepackage{X} ... """ println(s) ... \usepackage{X} ... Attempts so far include, scala> """\usepackage{X}""" <console>:1: error: error in unicode escape """\usepackage{X}""" ^ scala> raw"""\usepackage{X}""" <console>:1: error: error in unicode escape raw"""\usepackage{X}""" ^ Single double-quoted strings prove unsuccessful as well. Following http://docs.scala-lang.org/overviews/core/string-interpolation.html , a working example includes scala> raw"a\nb" res1: String = a\nb

I use python 2.7 and I'm receiving a string from a server (not in unicode!). Inside that string I find text with unicode escape sequences. For example like this: <a href = "http://www.mypage.com/\u0441andmoretext">\u00b2<\a> How do I convert those \uxxxx - back to utf-8? The answers I found were either dealing with &# or required eval() which is too slow for my purposes. I need a universal solution for any text containing such sequenes. Edit: <\a> is a typo but I want a tolerance against such typos as well. There should only be reaction to \u The example text is meant in proper python syntax

This question already has an answer here: Adding HTML entities using CSS content 9 answers I have a problem. I have found the HTML code for the downwards arrow, ↓ (↓) Cool. Now I need to use it in CSS like so: nav a:hover {content:"&darr";} That obviously won't work since ↓ is an HTML symbol. There seems to be less info about these "escaped unicode" symbols that are used in css. There are other symbols like \2020 that I found but no arrows. What are the arrow codes? Why don't you just save/serve the CSS file as UTF-8? nav a:hover:after { content: "↓"; } If that's not good enough, and you want
