Ah, yes, plaincharset. =)
That's basically a VERY small (4 classes) Charset, which I use to go
from byte[] to Java Strings without having to fuzz with the translation.
I'm going to write about this in my blog tonight, but anyway, here's the
short story:
char[] cs = new char[256];
for(int i=0;i<cs.length;i++) {
cs[i] = (char)i;
}
String str = String.valueOf(cs);
byte[] bts = str.getBytes(); // or str.getBytes("ASCII"); or
str.getBytes("UTF-8");
for(int i=0;i<256;i++) {
System.err.println("chr: " + (int)cs[i] + " byte: " + bts[i]);
}
What you will notice is a few places in the middle - different depending
on the encoding you choose when getting bytes - where the bytes are 63,
regardless of the char. This means that we cannot use this to represent
all bytes when we want to get at the underlying bytes. What plaincharset
does is (and it does it pretty fast) translate between char[] and byte[]
arrays such that for i in 0..255 byte[i] == (byte)char[i];
I need it desperately to handle IO work between Ruby-world and
Java-world, and it's probably useful in other places too. Use the
encoding named "PLAIN" and it just works (if plaincharset.jar is on the
classpath).
