问题 I have a problem with some German's special letters (ö, ü...) in my Laravel application. My encoding is set to UTF-8. Everything works fine with the content from the database (where is utf8_general_ci ). When I hardcode some text to Blade view files, that's fine, too. But, I'm using localization files ( /app/lang/de/myFile.php ) with an associative array. German characters from that array are displayed as � � �. What is strange, when I var_dump(trans('myFile.key')) in Blade, special

问题 I have a string which i want to save in a database that only supports UTF8 characters. If the string size is > 60 characters i want to truncate it and only store the first 60 characters. The Oracle database in use only supports UTF-8 characters. Using String.substring(0,59) in Java returns 60 characters but when i save it in the database it gets rejected as the database claims that the string is > 60 characters. Is there a way to find out if a particular string contains non UTF8 characters.

问题 I'm using a barcode scanner to read a barcode on my website (the website is made in OpenUI5). The scanner works like a keyboard that types the characters it reads. At the end and the beginning of the typing it uses a special character. These characters are different for every type of scanner. Some possible characters are: █ ▄ – — In my code I use if (oModelScanner.oData.scanning && oEvent.key == "\u2584") to check if the input from the scanner is ▄. Is there any way to get the code from that

问题 I am working on converting a string from one charset to another and read many example on it and finally found below code, which looks nice to me and as a newbie to Charset Encoding, I want to know, if it is the right way to do it . public static byte[] transcodeField(byte[] source, Charset from, Charset to) { return new String(source, from).getBytes(to); } To convert String from ASCII to EBCDIC , I have to do: System.out.println(new String(transcodeField(ebytes, Charset.forName("US-ASCII"),

问题 I have an xml string that is being posted to an ashx handler on the server. The xml string is built on the client-side and is based on a few different entries made on a form. Occasionally some users will copy and paste from other sources into the web form. When I try to load the xml string into an XMLDocument object using xmldoc.LoadXml(xmlStr) I get the following exception: System.Xml.XmlException = {"'', hexadecimal value 0x0B, is an invalid character. Line 2, position 1."} In debug mode I
