Method Detail

getDefaultEncoding

public static String getDefaultEncoding()

addEncodingAlias

public static void addEncodingAlias(String alias,
                                    String encoding)

Add alias for encoding name. Supposing that you want your custom JAPANESE_ENC to be mapped to EUC_JP (which is supported by Java), do as follows:

 CharIO.addEncodingAlias("JAPANESE_ENC", "EUC_JP");
 

Note that encoding must be the exactly the name Java knows about, for example "EUC_JP" is OK but "Euc_JP" is not! In the same time alias case does not matter: CharIO.addEncodingAlias("japanese_enc", "EUC_JP"); behaves exactly as the first example

createInputStreamReader

public static Reader createInputStreamReader(InputStream in,
                                             String enc)

If enc == null, assume value of getDefaultEncoding() Always supported values are "ISO8859_1", "UTF8", result of getDefaultEncoding() and their aliases

createInputStreamReader

public static Reader createInputStreamReader(InputStream in,
                                             String encArg,
                                             boolean deafultIfBadEncoding)

createURLReader

public static Reader createURLReader(URLConnection conn)
                              throws IOException

Throws:

IOException

getBreakIterator

public static BreakIterator getBreakIterator(Locale l)

getEncodingLanguage

public static String getEncodingLanguage(String encoding)

getEncodingLocale

public static Locale getEncodingLocale(String encoding)

getCharsetId

utf8ToStr

public static String utf8ToStr(byte[] array,
                               int offset,
                               int length)
                        throws IOException

Throws:

IOException

strToUTF8

public static byte[] strToUTF8(String str)

mapWin1252_128_159_toUnicode

public static int mapWin1252_128_159_toUnicode(int c)

Get Unicode character for Win1252 encoding code point c in range 128..159

Throws:

IllegalArgumentException - if c is outside 128..159
