It's 8-bit clean: the strings being processed may contain both null bytes and characters whose high bit is set. Regular -expression patterns may not contain null bytes, but they may contain -characters with the high bit set. The \module{re} module is always -available. +expression pattern strings may not contain null bytes, but can specify +the null byte using the \code{\e\var{number}} notation. +Characters with the high bit set may be included. The \module{re} +module is always available. Regular expressions use the backslash character (\character{\e}) to indicate special forms or to allow special characters to be used |
