Class OctalUnescaper
java.lang.Object
org.apache.commons.lang3.text.translate.CharSequenceTranslator
org.apache.commons.lang3.text.translate.OctalUnescaper
Deprecated.
As of 3.6, use Apache Commons Text
OctalUnescaper instead
Translate escaped octal Strings back to their octal values.
For example, "\45" should go back to being the specific value (a %).
Note that this currently only supports the viable range of octal for Java; namely
1 to 377. This is because parsing Java is the main use case.
