Eww, why would you do this? You're better off fixing your other tools that 
can't handle Unicode.

this is important to cjk non-unicode users
e.g. 
the page encoded in gbk
and wanted to export json data
servlet will encode json using gbk if not escaped

make all non ascii would be safe for javascript to use

jackson1.8 and php json_encode always have this feature

Its about an hour's work to make a Writer subclass that does what you'd like. 
There's no benefit to doing this in Gson directly.

... actually it was only about eight minutes work. Paste this class into your 
application (public domain license) and use it when you create your JsonWriter. 
There's some optimization opportunities if write() isn't fast enough; changes 
are it'll be fine.

public class GhettoAsciiWriter extends Writer {
    private final Writer out;

    public GhettoAsciiWriter(Writer out) {
        this.out = out;
    }

    @Override public void write(char[] buffer, int offset, int count) throws IOException {
        for (int i = 0; i < count; i++) {
            char c = buffer[i + offset];
            if (c <= 0x7f) {
                out.write(c);
            } else {
                out.write(String.format("\\u%04x", (int) c));
            }
        }
    }

    @Override public void flush() throws IOException {
        out.flush();
    }

    @Override public void close() throws IOException {
        out.close();
    }
}
