How do I make control characters programatically in Javascript?

In Javascript I can type '\u00A3' to get a character using its char code. I can do this programatically to with String.fromCharCode(parseInt('00A3', 16)). But I can't find a way to do the same for a control character. I can type them in my source code but I want a way to generate them in code.

iTextSharp and special characters (slovak graphemes)

I am having trouble with some special slovak characters (for example č, ň and ť). They are disappearing in the itextsharp generated pdf. From what I've been able to find, this problem has to do with encoding of my BaseFont. Currently I am using this: BaseFont.CreateFont(BaseFont.HELVETICA, iTextSharp.text.pdf.BaseFont.CP1250, BaseFont.NOT_EMBEDDED) Someone suggested that this should work: BaseFont.CreateFont(BaseFont.HELVETICA, iTextSharp.text.pdf.BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED) But it throws this exception error: System.ArgumentException was caught Message='Identity-H' is not a

I have a deployment script to which i have to pass LDAP password as cmd paramater. actual password: foo\$ser"ver\\ 1 (contains three space characters: at the beginning, before 1, and after 1) e.g ...bin>deployment.bat LDAPPassword= foo\$ser\"ver\\ 1 Note:There are spaces in the password as shown at the beginning.

Reading special characters like ÆØÅ into R (Rstudio)

I am trying to read a CSV file containing questionnaire data written in Norwegian. So this file contains the letters Æ Ø Å, however R does not seem to handle these letters well, they all appear as question marks. I use this to read the data: data <- read.csv2("Responser - Vasket - 20.06.2013.csv") Is there any options I should use to let R know I have special characters? and I am using Rstudio on Windows 7.

I have a problem with a search with special characters in solr. My document has a field "title" and sometimes it can be like "Titanic - 1999" (it has the character "-"). When i try to search in solr with "-" i receive a 400 error. I've tried to escape the character, so I tried something like "-" and "\-".

Importing data with special characters in R

The following pic shows how the data is before i import it(notepad) in R and after importing. I use the following command to import it in R: Data <- read.csv('data.csv',stringsAsFactors = FALSE,header = TRUE,quote = "") It can be seen that the special characters such as the ae is replaced with something like A| (line 19 on the left,line 18 or the right). Is there a way to import the CSV file as it is? (Using R)

How do you cope with signed char -> int issues with standard library?

This is a really long-standing issue in my work, that I realize I still don't have a good solution to... C naively defined all of its character test functions for an int: int isspace(int ch); But char's are often signed, and a full character often doesn't fit in an int, or in any single storage-unit that used for strings******. And these functions have been the logical template for current C++ functions and methods, and have set the stage for the current standard library. In fact, they're still supported, afaict. So if you hand isspace(*pchar) you can end up with sign extension problems. They
