 * characters the same, and substitutes "?\\XXX" for others, where XXX
 * is the unsigned decimal code for that character.
 *
 * This function cannot error; it is guaranteed to return something.
 * First it will recode as described above and then attempt to convert
 * the (new) 7-bit UTF-8 string to native encoding.  If that fails, it
 * will return the raw fuzzily recoded string, which may or may not be
 * meaningful in the client's locale, but is (presumably) better than
 * nothing.
 *
 * ### Notes:
 *
 * Improvement is possible, even imminent.  The original problem was
 * that if you converted a UTF-8 string (say, a log message) into a
 * locale that couldn't represent all the characters, you'd just get a
 * static placeholder saying "[unconvertible log message]".  Then
 * Justin Erenkrantz pointed out how on platforms that didn't support
 * conversion at all, "svn log" would still fail completely when it
 * encountered unconvertible data.
 *
 * Now for both cases, the caller can at least fall back on this
 * function, which converts the message as best it can, substituting
 * "?\\XXX" escape codes for the non-ascii characters.
 *
 * Ultimately, some callers may prefer the iconv "//TRANSLIT" option,
 * so when we can detect that at configure time, things will change.
 * Also, this should (?) be moved to apr/apu eventually.
 *
 * See https://issues.apache.org/jira/browse/SVN-807 for
 * details.
