Subject [jira] Commented: (LUCENE-1241) 0xffff char is not a string terminator
Date Fri, 21 Mar 2008 16:15:27 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1241?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581110#action_12581110

Steven Rowe commented on LUCENE-1241:
-------------------------------------

bq. we can't handle a string that really contains \uffff

This is an invalid UTF16 string for interchange. The standard explicitly allows for certain
characters (including this one) to be used for internal purposes.

I strongly suspect, however, that "internal purposes" is meant to be taken as application-internal,
not leaf-library-internal.

> Current trunk index.DocumentWriter uses "\uffff" as a string terminator, but it should
not to be for some reasons. \uffff is not a terminator char itself and we can't handle a string
that really contains \uffff. And also, we can calculate the end char position in a character
sequence from the string length that we already know.
> However, I agree with the usage for assertion, that "\uffff" is placed after at the end
of a string in a char sequence.
