Subject [jira] Commented: (LANG-498) Add StringEscapeUtils.escapeText() methods
Date Wed, 24 Jun 2009 05:02:07 GMT

    [ https://issues.apache.org/jira/browse/LANG-498?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12723438#action_12723438
] 

Henri Yandell commented on LANG-498:
------------------------------------

This would now be implemented as:

        new AggregateTranslator(
            new EscapeLowAsciiAsUnicode(),
            new EscapeNonAsciiAsUnicode()
        );

Not escaping \ would still leave it one-way. Possibly that would become:

  static import org.apache.commons.lang.text.translate.EscapeUtils.*;

  TRANSLATE.with(ASCII_LOW, ASCII_GREATER_THAN)

Though that all has the assumption that \b is the escape for backspace and not the unicode
value for the number etc.

Alternatively, it would not be a huge change for this to be doable:

  UnicodeEscaper.below(32).with(UnicodeEscaper.above(0x7f));

if \b should go to unicode etc.

> I needed to escape text to be print out to a file; mainly so that all non-ASCII characters
(< 32 and >=127) are printed out as escapes (if available) or unicode escapes. This
is a one-way conversion, there is no way to find out whether a String contained "\\n" or a
newline before conversion, so I just set up escapeText() methods, no unescapeText(). 
> Please apply to the next release of commons-lang. :-)
