耗尽温柔 提交于 2019-12-03 15:44:36
问题 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!! 回答1: 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,

How to add a carriage return as a character to a file?

I wanna have a string like: blablbabla<carriage return goes here> I mean the string should contain the carriage return. Is there any simple way to do it? Or if a write a program in c and use fputs with blablabla\r , does this do the trick? Jeff Ferland If you're using vim you can enter insert mode and type 'CTRL-v CTRL-m'. That ^M is the keyboard equivalent to \r. (see Insert the carriage return character in vim ) Inserting 0x0D in a hex editor will do the task. echo -ne "blablbabla\r" > /path/to/your/file SHELLVAR=$(echo -ne "blablabla\r") See the echo man page — the -e option causes echo to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last year . 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

php with special characters like ñ

微笑、不失礼 提交于 2019-12-03 13:36:18
问题 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

How to show superscript for “®” registered symbol?

徘徊边缘 提交于 2019-12-03 10:54:05
I've a issue regarding showing registered symbol as superscript. I've used unicode value \u00AE, but it shows in same line. I'd like to have it a bit top of remaining texts. Done googling, but found superscripts for A-Z, 0-9 characters, which is mentioned in unicode's site. Sample code: UILabel *myLabel; //do initialize stuff here myLabel.text = @"My company\u00AE"; Thanks sorin Unicode does not have a registered symbol in superscript form so the only way to do it is to use a HTML control and to include it into superscript tags: <sup>®</sup> You can check it at http://rishida.net/scripts

问题 I want to create a database which name will have special characters in it. for example, (., - , _, @, #, $, %, &, *) can anyone provide any output on this? 回答1: I would strongly recommend that you do not create databases with such names. But if you absolutely must, here are the restrictions: No identifier can contain ASCII NUL (0x00) or a byte with a value of 255. Database, table, and column names should not end with space characters. Database and table names cannot contain “/”, “\”, “.”, or

Wordpress search failed on special characters due to improper decode

百般思念 提交于 2019-12-03 08:29:51
问题 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

How do I make eclipse print out weird characters in unicode?

假装没事ソ 提交于 2019-12-03 07:16:20
So I'm trying to make my program output a text file with a list of names. Some of the names have weird characters, such as Åström. I have grabbed these list of names from a webpage that is encoded in "UTF-8", or at least I'm pretty sure it does because the page source says " meta http-equiv="Content-Type" content="text/html; charset=UTF-8" / " This is what I've tried so far: public static void write(List<String> list) throws IOException { Writer out = new OutputStreamWriter(new FileOutputStream("test.txt"), "UTF-8"); try { for (int i=0;i<list.size();i++) { try { byte[] utf8Bytes = list.get(i)

醉酒当歌 提交于 2019-12-03 06:50:02
问题 I saw mention of the term, along with CRLF, CR, LF, CTL (control characters) and SP (space). If it's not the regular inline whitespace ( ), so what character(s) is it? 回答1: From STD68 Augmented BNF for Syntax Specifications: ABNF LWSP = *(WSP / CRLF WSP) ; Use of this linear-white-space rule permits ; lines containing only white space* WSP = SP / HTAB ; white space CRLF = CR LF ; Internet standard newline SP = %x20 ; space HTAB = %x09 ; horizontal tab CR = %x0D ; carriage return LF = %x0A ;

Escaping special character when generating an XML in Java

你说的曾经没有我的故事 提交于 2019-12-03 06:36:50
问题 I am trying to develop an XML export feature to give my application users to export their data in an XML format. I have got this feature ready and working until it started failing for some cases. Then I realized that it was because of some special characters that needs to be encoded. for example the data might contain & or ! or % or ' or # etc. etc. and this needs to be escaped properly. I was wondering if there is a generic utility available that can escape all of the special characters as
