escaping

CGI.escapeHTML is pretty bad, but CGI.unescapeHTML is completely borked. For example: require 'cgi' CGI.unescapeHTML('…') # => "…" # correct - an ellipsis CGI.unescapeHTML('…') # => "…" # should be "…" CGI.unescapeHTML('¢') # => "\242" # correct - a cent CGI.unescapeHTML('¢') # => "¢" # should be "\242" CGI.escapeHTML("…") # => "…" # should be "…" It appears that unescapeHTML knows about all of the numeric codes plus & , < , > , and " . And escapeHTML only knows about those last four -- it doesn't do any of the numeric codes. I understand that escaping doesn't generally need to be as robust

I'm setting document.title with JavaScript, and I can't find a way to supply » ( &raquo ) without it appearing as literal text. Here's my code: document.title = 'Home » site.com'; If I use &raquo ; in the title tag of the document it works great and displays correctly as », but it seems to be unescaping when I include it in document.title . Any ideas? thanks! Try document.title = 'Home \u00bb site.com'; Generally you can look up your special character at a site like this and then, once you know the numeric code, you can construct a Unicode escape sequence in your JavaScript string. Here, that

I've got a report that's supposed to take a grid control and produce HTML output. One of the columns in the grid can display any of a number of values, or <Any> . When this gets output to HTML, of course, it ends up blank. I could probably write up some routine to use StringReplace to turn that into <Any> so it would display this particular case correctly, but I figure there's probably one in the RTL somewhere that's already been tested and does it right. Anyone know where I could find it? I am 99 % sure that such a function does not exist in the RTL (as of Delphi 2009). Of course - however -

We implemented the online service where it is possible to generate PDF with predefined structure. The user can choose a LaTeX template and then compile it with an appropriate inputs. The question we worry about is the security, that the malicious user was not able to gain shell access through the injection of special instruction into latex document. We need some workaround for this or at least a list of special characters that we should strip from the input data. Preferred language would be PHP, but any suggestions, constructions and links are very welcomed. PS. in few word we're looking for

Basically, what I'd like to do is have: // in foo.scala val string = "this is a string\nover two lines" println(string) println(foo(string)) Do this: % scala foo.scala this is a string over two lines "this is a string\nover two lines" Basically looking for an analog of ruby's String#inspect or haskell's show :: String -> String . This question is a bit old but I stumbled over it while searching for a solution myself and was dissatisfied with the other answers because they either are not safe (replacing stuff yourself) or require an external library. I found a way to get the escaped

I'm having trouble converting a string with escaped characters to and from a TJsonString. (I'm using Delphi XE 2, Update 4, Hotfix 1). NOTE: I am familiar with the SuperObject , but my requirements are to use the DBXJSON unit. It looks like the TJSONString is not correctly escaped when returning the JSON representation via the ToString() method. What (if anything) am I doing wrong and how do I correctly convert a string with special characters to/from its correct JSON representation? Perhaps I missed something, but none of the following Q&As seemed to address this directly: Delphi decode json
