Escape Unicode Characters In Java Strings

Stefan Soher — Tue, 07 Sep 2010 12:49:21 +0000

I was looking for a code snippet that does that for me but couldn’t find one. If you’re in a similar situation, feel free to use this:

package at.soher.unicode;

import java.text.NumberFormat;

public class StringEscape {

    public static void main(String[] args) {

        String input = args[0];
        char[] dst = new char[input.length()];
        input.getChars(0, input.length(), dst, 0);
        StringBuilder dest = new StringBuilder();
        NumberFormat numberFormat = NumberFormat.getIntegerInstance();
        numberFormat.setMinimumIntegerDigits(4);
        numberFormat.setGroupingUsed(false);
        for (int i = 0; i < dst.length; i++) {
            if(dst[i]>127) {
                dest.append("\\u" + numberFormat.format((int)dst[i]));
            } else {
                dest.append(dst[i]);
            }
        }
        System.out.print(dest.toString());
    }
}

Prague

At the beginning of the month, I spent a few days in Prague. Here are a few impressions.

March and Rally for Human Rights at AIDS 2010

Stefan Soher — Sun, 25 Jul 2010 17:39:49 +0000

Last week, the XVIII International AIDS Conference (AIDS 2010) took place in Vienna. Part of it was a rally for human rights on the 20th of July, which was headed by singer Annie Lennox, who also performed. I was there and took a few pictures. Please also take some time and read about the current struggle against HIV/AIDS and the 10 reasons why human rights should occupy the center of the global AIDS struggle.

Riesenrad, again

Stefan Soher — Mon, 21 Jun 2010 21:45:00 +0000

Some might think it’s sad that I came from work only after dark on the longest day of the year, but it gave me the opportunity to get these pictures of the Riesenrad.

Hear Me Sing

Stefan Soher — Fri, 18 Jun 2010 21:52:18 +0000

Last night I went to choir practice for the first time in over a year. Mentioning the fact on twitter naturally led to the question what we do, so I went on youtube to see if they had a few examples of the music we like. Turns out they had, and not just of the music, but also of us performing.

A word of caution: These are random recordings that don’t show us at our best; although I really don’t think youtube is right to link to Jimmy’s Infantile Spasms in the related videos column.

In 2009, a few of us went to Milan to take part in a festival called Politicanto. It was great fun and we met a lot of wonderful people there.

In Vienna, every Friday the 13th is celebrated in it’s own unique way. It’s about having fun, but it’s also a political statement, taking back the public space and making parts of society visible that tends to stay hidden.

Summer in Vienna, part four

Today, I tried to find a few locations to see Vienna from above. The city is not known for its many skyscrapers. There are a few elevated places, however.

Of course, a blog post like this could never be complete without a few pictures of the Riesenrad.

Tiergarten Schönbrunn, part two

@kevay and I spent another pleasant afternoon at the zoo. I have no illusions as to how much I suck at photography, but maybe you would like to have a peek anyway.

My Trip to Berlin

Stefan Soher — Mon, 04 Jan 2010 21:27:32 +0000

I spent the days between Christmas and the New Year in Berlin. The weather was horrible, so I stayed indoors most of the time. That gave me ample opportunity to play with the new camera I got for Christmas in an environment with which I’m as yet totally unfamiliar.

Who would have thought London Transport would have a station in Berlin.

Haus des Lehrers (Teacher's House) in Berlin, Alexanderplatz. A good example of GDR post-war architecture, the house was built as a replacement for the earlier Lehrervereinshaus.

Hello, Mr Crab.

Can you see it?

Are you watching me?

Just because I look like a leaf doesn't mean I have no feelings!

Vienna Opera House (Detail)

Albertinaplatz

Hofburg/Josefsplatz

The Michaelertor is the "backdoor" of the Hofburg, the former residence of the emperor.

The Michaelertor is accompanied by two fountains. This is the one nearer Augustinerstraße.

The Looshaus, constructed in 1909 by architect Adolf Loos, is one of the beacons of the Wiener Moderne, or Viennese Modern Age.
