Check your system locale. Then use a matching command line

问题 This should be possible, but as I am a novice with m4, I'm not sure how to go about it, or how to write an algorithm to do so (in m4). edit: Just solved it, anyway for future reference, I have a series of characters, they need to be translated to their equivalent ASCII code points, e.g. ascii(-{COLON}-, -{:}-) => #define TKN_COLON 58 回答1: For the benefit of others interested in a pure m4 implementation I've managed to create the following conversion macro. It has to meddle with the quoting

问题 I was reading this Should source code be saved in UTF-8 format and I am using the eclipse compiler lib but need to read some java source files in to feed it to that library. IT seems it can be stored in different formats from that post. Is there one Charset I can use to read it in so it works every time. Charset.forName("UTF-8") maybe? thanks, Dean 回答1: Character encodings vary Any tool can write Java source code in any encoding. Even the idea of .java file is not defined by the Java Language

问题 My installator (Inno Setup) has a bad Russian text encoding for the some Windows installations. All machines have Windows XP SP3 (English version), but on some this works, some does not have. There are any settings on Windows to fix it? Thanks 回答1: My guess is that you are using the Non-Unicode version of Inno Setup. The machines, where the installer has wrong encoding, probably do not have the Russian set as the legacy (non-Unicode) encoding. In Windows XP Control panel, check the "Regional

问题 What's the command to set the JVM's character set? (Also, what's the command to view the current JVM's character set, so I know how to reset it back to default after I'm done) Thanks, 回答1: java strings are always utf-16 internally (javadoc link), but you can use -Dfile.encoding=UTF-8 to facilitate reading files with a default charset. Just ensure java has access to that fileset when you set it or it won't start. 回答2: java.nio.charset.Charset.defaultCharset() Will get you the JVM's default

问题 When I use UTF-8 characters (most of the time Turkish characters) in controllers, I have to add #encoding: utf-8 on the top of each controller file. Why doesn't Rails use this as a default? edit: I have learnt that it is not about Rails, it is about Ruby. 回答1: Ruby 2.0 is UTF8 by default. Otherwise you must signify that in 1.9. According to naruse: The default script encoding change. Default script encoding (when magic comment is not specified) is changed into UTF8[#6679] In Ruby 1.9, the

问题 I have some strings in dutch language. I know how to encode them using PHP $str = iconv( "Windows-1252", "UTF-8", $str ); What would be the equivalent in Javascript? 回答1: Windows-1252 is a single-byte encoding, which is pretty convenient: you can just build a lookup table. <?php $s = ''; for ($i = 0; $i < 256; $i++) { $converted = iconv('Windows-1252', 'UTF-8', chr($i)); if ($converted === false) { $s .= "\xef\xbf\xbd"; # UTF-8 replacement character } else { $s .= $converted; } } echo $s;

问题 I'm having strange issue with a response got from API. I'm using apache HTTP Client to get response. Response header has the following Content-Type=[application/json; charset=utf-16] Transfer-Encoding=[chunked] X-Powered-By=[ASP.NET] // Yes, people using ASP.NET So based on this, when I get response, my response looks like follows 笀∀匀琀愀琀甀猀䌀漀搀攀∀㨀㈀　 So I tried the following. String body = "笀∀匀琀愀琀甀猀䌀漀搀攀∀㨀㈀"; String charSetString = "utf-8|utf-16|utf-16le, all possible combination" body = new

问题 Currently, I have my webpage set to Unicode/UTF-8. When trying to display a special character (for example, em dash, double arrow, etc), it shows up as a question mark symbol. I cannot change these characters to the HTML entity equivalent. How can I circumvent this issue? 回答1: A question mark in a lozenge, �, indicates a character-level error: the data contains bytes that do no represent any character, according to the character encoding being applied. This typically happens when the document
