getZipEncoding
public static ZipEncoding getZipEncoding(java.lang.String name)
Instantiates a ZIP encoding. An NIO based character set encoder/decoder will be returned. As a special case, if the character set is UTF-8, theNIOencoder will be configured replace malformed and unmappable characters with '?'. This matches existing behavior from the older fallback encoder.If the requested character set cannot be found, the platform default will be used instead.
- Parameters:
name
- The name of the ZIP encoding. Specifynull
for the platform's default encoding.- Returns:
- A ZIP encoding for the given encoding name.
-
growBufferBy
static java.nio.ByteBuffer growBufferBy(java.nio.ByteBuffer buffer, int increment)
-
isUTF8
static boolean isUTF8(java.lang.String charsetName)
Tests whether a given encoding is UTF-8. If the given name is null, then check the platform's default encoding.- Parameters:
charsetName
