Method

StringencodeFilenameOmittingWhiteSpaces(String filename, String encoding)
encode Filename Omitting White Spaces 
if (filename == null || filename.length() == 0)
    return "";
else {
    int index = filename.indexOf(' ');
    if (index == -1) {
        return encodeFilename(filename, encoding);
    } else {
        return URLEncoder.encode(filename.substring(0, index), encoding) + " "
...
StringencodeForm(Map form)
encode Form 
try {
    StringBuilder result = new StringBuilder();
    for (Entry<String, Object> argument : form.entrySet()) {
        result.append(URLEncoder.encode(argument.getKey(), "UTF-8"));
        result.append('=');
        result.append(URLEncoder.encode(String.valueOf(argument.getValue()), "UTF-8"));
        result.append('&');
    result.deleteCharAt(result.length() - 1);
    return result.toString();
} catch (UnsupportedEncodingException e) {
    throw new IllegalStateException(e);
StringencodeIncludingSpecialCharacters(String toEncode)
Some calls in the Heroku API decode strings in a different way from URLEncoder. 
String encoded = urlencode(toEncode, "Unable to urlencode " + toEncode);
for (Map.Entry<String, String> s : specialChars.entrySet()) {
    encoded = encoded.replace(s.getKey(), s.getValue());
return encoded;
StringencodeInternally(String s)
encode Internally 
try {
    return URLEncoder.encode(s, "UTF8");
} catch (UnsupportedEncodingException e) {
    throw new UncheckedIOException(e);
StringencodeJobHistoryFileName(String logFileName)
Helper function to encode the URL of the filename of the job-history log file. 
String replacementDelimiterEscape = null;
if (logFileName.contains(DELIMITER_ESCAPE)) {
    replacementDelimiterEscape = nonOccursString(logFileName);
    logFileName = logFileName.replaceAll(DELIMITER_ESCAPE, replacementDelimiterEscape);
String encodedFileName = null;
try {
    encodedFileName = URLEncoder.encode(logFileName, "UTF-8");
...
voidencodeMap(Map map, String enc)
encode Map 
if (null != map) {
    Set<String> keySet = map.keySet();
    for (String key : keySet) {
        if (key.equals("sign") || key.equals("sign_type")) {
            continue;
        } else {
            try {
                map.put(key, URLEncoder.encode(map.get(key) + "", enc));
...
StringencodeName(final String name)
encode Name 
try {
    return URLEncoder.encode(name, "UTF-8");
} catch (UnsupportedEncodingException e) {
    throw new IllegalStateException(
            "Unsupported UTF-8 charset. Scenarioo needs to run on a JVM or server environment that supports 'UTF-8'.",
            e);
StringencodeName(String createdName)
encode Name 
try {
    return URLEncoder.encode(URLEncoder.encode(createdName, "UTF-8"), "UTF-8");
} catch (final UnsupportedEncodingException e) {
    e.printStackTrace();
return createdName;
StringencodeParameter(String key, String value)
Encodes to given key to:

= 

StringBuffer sb = new StringBuffer();
sb.append(encode(key));
sb.append("=");
sb.append(encode(value));
return sb.toString();
StringencodeParameters(Map> parameters)
Returns a properly encoded string of parameters. 
if (parameters == null) {
    return "";
StringBuilder b = new StringBuilder();
boolean first = true;
for (String key : parameters.keySet()) {
    if (!first) {
        b.append("&");
