Question:
How to list all character sets supported by a JVM?
Code:
import java.util.Map; import java.nio.charset.Charset; import java.util.Set; public class AvailableCharsets { public static void main(String[] args) { Map<String, Charset> map = Charset.availableCharsets(); Set<String> keys = map.keySet(); for (String charsetName : keys) { System.out.println(charsetName); } } }
Output:
$ java AvailableCharsets Big5 Big5-HKSCS EUC-JP EUC-KR GB18030 GB2312 GBK IBM-Thai IBM00858 IBM01140 IBM01141 IBM01142 IBM01143 IBM01144 IBM01145 IBM01146 IBM01147 IBM01148 IBM01149 IBM037 IBM1026 IBM1047 IBM273 IBM277 IBM278 IBM280 IBM284 IBM285 IBM290 IBM297 IBM420 IBM424 IBM437 IBM500 IBM775 IBM850 IBM852 IBM855 IBM857 IBM860 IBM861 IBM862 IBM863 IBM864 IBM865 IBM866 IBM868 IBM869 IBM870 IBM871 IBM918 ISO-2022-CN ISO-2022-JP ISO-2022-JP-2 ISO-2022-KR ISO-8859-1 ISO-8859-13 ISO-8859-15 ISO-8859-2 ISO-8859-3 ISO-8859-4 ISO-8859-5 ISO-8859-6 ISO-8859-7 ISO-8859-8 ISO-8859-9 JIS_X0201 JIS_X0212-1990 KOI8-R KOI8-U Shift_JIS TIS-620 US-ASCII UTF-16 UTF-16BE UTF-16LE UTF-32 UTF-32BE UTF-32LE UTF-8 windows-1250 windows-1251 windows-1252 windows-1253 windows-1254 windows-1255 windows-1256 windows-1257 windows-1258 windows-31j x-Big5-HKSCS-2001 x-Big5-Solaris x-COMPOUND_TEXT x-euc-jp-linux x-EUC-TW x-eucJP-Open x-IBM1006 x-IBM1025 x-IBM1046 x-IBM1097 x-IBM1098 x-IBM1112 x-IBM1122 x-IBM1123 x-IBM1124 x-IBM1364 x-IBM1381 x-IBM1383 x-IBM300 x-IBM33722 x-IBM737 x-IBM833 x-IBM834 x-IBM856 x-IBM874 x-IBM875 x-IBM921 x-IBM922 x-IBM930 x-IBM933 x-IBM935 x-IBM937 x-IBM939 x-IBM942 x-IBM942C x-IBM943 x-IBM943C x-IBM948 x-IBM949 x-IBM949C x-IBM950 x-IBM964 x-IBM970 x-ISCII91 x-ISO-2022-CN-CNS x-ISO-2022-CN-GB x-iso-8859-11 x-JIS0208 x-JISAutoDetect x-Johab x-MacArabic x-MacCentralEurope x-MacCroatian x-MacCyrillic x-MacDingbat x-MacGreek x-MacHebrew x-MacIceland x-MacRoman x-MacRomania x-MacSymbol x-MacThai x-MacTurkish x-MacUkraine x-MS932_0213 x-MS950-HKSCS x-MS950-HKSCS-XP x-mswin-936 x-PCK x-SJIS_0213 x-UTF-16LE-BOM X-UTF-32BE-BOM X-UTF-32LE-BOM x-windows-50220 x-windows-50221 x-windows-874 x-windows-949 x-windows-950 x-windows-iso2022jp
