[icu-support] question on performance of character searching in UnicodeString

[Wang, J. <jw...@pa...>]

We are trying to log a warning message whenever a Unicode substitution
character 0xFFFD or windows-1252 substitution character 0x1A is found in
data. Because we would like to check all textual data in/out of DB, we
have concern with the performance of UnicodeString.indexOf()? Will using
regular expression help the performance?
