special-characters

Simply i want to replace a character with another in android.. My code: et = (EditText) findViewById(R.id.editText1); String str = et.getText().toString(); str.replace(' ','_'); et.setText(str); System.out.println(str); But here the "space" is not replaced by "underscore".. I also tried other character too.. please help!! Strings are immutable in Java - replace doesn't change the existing string, it returns a new one. You want: str = str.replace(' ','_'); (This is definitely a duplicate, but I don't have enough time right now to find an appropriate one...) String is immutable and you cannot

I want to remove all special characters from a string. Allowed characters are A-Z (uppercase or lowercase), numbers (0-9), underscore (_), white space ( ), pecentage(%) or the dot sign (.). I have tried this: StringBuilder sb = new StringBuilder(); foreach (char c in input) { if ((c >= '0' && c <= '9') || (c >= 'A' && c <= 'Z') || (c >= 'a' && c <= 'z') | c == '.' || c == '_' || c == ' ' || c == '%') { sb.Append(c); } } return sb.ToString(); And this: Regex r = new Regex("(?:[^a-z0-9% ]|(?<=['\"])s)", RegexOptions.IgnoreCase | RegexOptions.CultureInvariant | RegexOptions.Compiled); return r

I sometimes need to look for information for a special portion of code. When this code concerns or contains a special character ( ° , * , # , ... etc), that is not always recognized in search engines, I often end up having to ask a new question because I do not know how to write these characters in plain text. Can anybody give me a link to a sort of English dictionary of all these signs and symbols? You need the Jargon file . Amongst al the fantastic definitions (in the glossary section) is a list of ASCII symbols and what they're called. Sadly, a lot of these characters have multiple names,

At first I thought the problem was when I return echo json_encode($row) from an ajax call that results with ñ are changed to NULL. But after testing I found out that the problem exists way before that. In a sample php file with: $test = "Nuñez" echo $test the result is just Nu�ez I've searched around but none of the suggested solutions work. Like: mb_internal_encoding('UTF-8'); mb_http_output('UTF-8'); mb_http_input('UTF-8'); mb_language('uni'); mb_regex_encoding('UTF-8'); ob_start('mb_output_handler'); or <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> , or header(

I have been given an export from a MySQL database that seems to have had it's encoding muddled somewhat over time and contains a mix of HTML char codes such as & uuml; and more problematic characters representing the same letters such as ü and à . It is my task to to bring some consistency back to the file and get everything into the correct Latin characters, e.g. ú and ó . An example of the sort of string I am dealing with is Desinfektionslösungstücher für Flächen Which should equate to 50 Tattoo Desinfektionsl ö sungst ü cher f ü r Fl ä chen 50 Tattoo Desinfektionsl ö sungst

In Ruby, a standard convention is to use a question mark at the end of a method name to indicate the method returns a boolean result: [].empty? #=> true Another standard convention is to end a method name with an exclamation point if the method is destructive (that is, it modifies the original data): mylist.sort! # sort mylist in-place Recently I have seen these same conventions used in Scheme. Which makes me wonder, what other languages use/support this convention? Are there any other special characters that are commonly used for naming by these or other languages? The answer is, of course,

I am implementing the Wordpress search functionality. When I search for text " Division's " (which is a text in one of the posts), It returns "No results found" Now to investigate further, I checked the core file: wp-includes/query.php => function parse_search() And found that the $term is received encoded as : Division\xe2\x80\x99s Now this term is not decoded properly. And the final SQL statement formed is : (((test_posts.post_title LIKE '%Division\xe2\x80\x99s%') OR (test_posts.post_content LIKE '%Division\xe2\x80\x99s%'))) So, I want to decode the special characters to succesfully search

I am pulling in some information from a database that contains dimensions with both ' and " to denote feet and inches. Those characters being in my string cause me problems later and I need to replace all of the single and double quotes. I can successfully get rid of one or the other by doing: this.Vals.replace(/\'/g, "") To get rid of single quotes or this.Vals.replace(/\"/g, "") To get rid of double quotes How do I get rid of both of these in the same string. I've tried just doing this.Vals.replace(/\"'/g, "") and this.Vals.replace(/\"\'/g, "") But then neither get replaced. You don't escape
