[forge-issues] [JBoss JIRA] (FORGE-895) Shell crops Strings with UTF-8 charaters

------------------------------------

             Summary: Shell crops Strings with UTF-8 charaters
                 Key: FORGE-895
                 URL: https://issues.jboss.org/browse/FORGE-895
             Project: Forge
          Issue Type: Bug
          Components: UI - Shell
    Affects Versions: 1.2.3.Final
            Reporter: Florian Hirsch
            Priority: Minor


when I try to print some UTF-8 characters in the shell the end of the line is cropped. E.g.
{code}
shell.print("\u2501 Hello World"); 
{code}
results in
{code}
━ Hello Wor
{code}

Looks like the org.jboss.forge.shell.buffers.JLineScreenBuffer is calculating the BufferSize wrong:

{code}
public synchronized void write(String s) {
      if (bufferSize + s.length() >= maxBufferSize)
      {
         flushBuffer();
         write(s);
      }

      buffer.put(s.getBytes());
      bufferSize += s.length();
      _flush();
}
{code}

s.length() is returning the size of the used Characters, not the Size of the used Bytes. Could be replaced by s.getBytes("UTF-8").length or e.g. [this calculation method|http://stackoverflow.com/questions/8511490/calculating-length-in-utf-8-of-java-string-without-actually-encoding-it/8512877#8512877]
