special-characters

I am doing some work for a French client and so need to deal with accented characters. But I'm running into a lot of difficulty, I am hoping the solution is simple and that somebody can point it out to me. The string: La Forêt pour Témoin is converted to: La For? pour T?oin Note the missing character following the accented character - the t following the ê and the m following the é . I have tried using StringEscapeUtils which was successful at escaping some characters, such as ă . I have also built my own escape function which produces the same results ( ă will work, ê will not). private

I'm working on a long string grabbed from a Session that uses "§" (Section sign) to group and divide different parts of the string. Example: "ArticleID | Title | Date § ArticleID | Title | Date § ArticleID | Title | Date" I want to put this into an array using: explode("§",$str); However, for some reason the character is totally ignored. I have simply used a different character instead to get this working but why does PHP not recognise it? Check the file encoding. This § can be being passed to explode() as "\xA7", "\xA7\x00" or "\xC2\xA7" depending if the PHP file is encoded as ASCII, UNICODE

Can anyone suggest me how to check if a String contains full width characters in Java ? Characters having full width are special characters. Full width characters in String: ａｂｃ＠ｇｍａｉｌ.ｃｏｍ Half width characters in String: abc@gmail.com I'm not sure if you are looking for any or all, so here are functions for both: public static boolean isAllFullWidth(String str) { for (char c : str.toCharArray()) if ((c & 0xff00) != 0xff00) return false; return true; } public static boolean areAnyFullWidth(String str) { for (char c : str.toCharArray()) if ((c & 0xff00) == 0xff00) return true; return false; } As

I have a website where I've used php to include sections rather than having code be duplicated for each page. However, recently my webhost upgraded the PHP to 5.6, and now all my Æ, Ø and Å's give me the replacement character (�). I'm not running any databases, and setting a charset in the html didn't help. I'm very inexperienced with PHP, so I have no idea how to fix it. Please, any help would be great! I had the same problem after upgrading from php 5.5. to 5.6. Solved it by setting the default_charset to an empty string in my script: ini_set("default_charset", ""); Or if you have acceess to

I have a csv file where column names include spaces and special characters. fread imports them with quotes - but how can I change this behaviour? One reason is that I have column names starting with a space and I don't know how to handle them. Any pointers would be helpful. Edit: An example. > packageVersion("data.table") [1] ‘1.8.8’ p2p <- fread("p2p.csv", header = TRUE, stringsAsFactors=FALSE) > head(p2p[,list(Principal remaining)]) Error: unexpected symbol in "head(p2p[,list(Principal remaining" > head(p2p[,list("Principal remaining")]) V1 1: Principal remaining > head(p2p[,list(c(

I use these lines of code to remove all punctuation marks, symbols, etc as you can see them in the array, $pattern_page = array("+",",",".","-","'","\"","&","!","?",":",";","#","~","=","/","$","£","^","(",")","_","<",">"); $pg_url = str_replace($pattern_page, ' ', strtolower($pg_url)); but I want to make it simpler as it looks silly to list all the stuff I want to remove in the array as there might be some other special characters I want to remove. I thought of using the regular expression below, $pg_url = preg_replace("/\W+/", " ", $pg_url); but it doesn't remove under-score - _ What is the
