Duncan Jones created LANG-1294:
----------------------------------
Summary: WordUtils.capitalize() can't handle 1:M conversions
Key: LANG-1294
URL: https://issues.apache.org/jira/browse/LANG-1294
Project: Commons Lang
Issue Type: Bug
Components: lang.text.*
Affects Versions: 3.5
Reporter: Duncan Jones
Some case conversions are not 1:1, for instance the German letter ß, which is
normally capitalised to 'SS'.
{code:java}
// Failing test
assertEquals("SS", WordUtils.capitalize("\u00DF"));
{code}
If we were using upper case and not title case, a solution such as the
following would work:
{code:java}
public static String capitalize(final String str, final char... delimiters) {
final int delimLen = delimiters == null ? -1 : delimiters.length;
if (StringUtils.isEmpty(str) || delimLen == 0) {
return str;
}
final StringBuffer buffer = new StringBuffer(str.length());
final char[] chars = str.toCharArray();
boolean capitalizeNext = true;
for (int i = 0; i < chars.length; i++) {
final char ch = chars[i];
if (isDelimiter(ch, delimiters)) {
capitalizeNext = true;
buffer.append(ch);
} else if (capitalizeNext) {
// Use ENGLISH locale to be backwards compatible with previous
releases, which
// used Character.toUpperCase()
buffer.append(String.valueOf(ch).toUpperCase(Locale.ENGLISH));
capitalizeNext = false;
} else {
buffer.append(ch);
}
}
return buffer.toString();
}
{code}
... but as we use title case, we can't use the String class to convert for us.
