That's quite old. Current release is 7.4 (September 2007). My testing
using pcretest shows that this works:
re> /\x{c4}/8i
data> \x{c4} 0: \x{c4} data> \x{e4} 0: \x{e4}
That is using the hex values for A-umlaut and a-umlaut. But it also
works with the binary, provided that you are using UTF-8 strings. That
is, A-umlaut is encoded as the two bytes C3 84 and a-umlaut is C3 A4.
