# These tests use the following unicode characters in various ways:
# GREEK CAPITAL LETTER PHI (U+03A6)
# UTF-8: hex: 0xCE 0xA6
# oct: 0316 0246
# bin: 11001110 10100110

# Using the first octet alone (\316) causes various multibyte related functions
# to return '-2' (incomplete multibyte sequence).
# using the second octet alone (\246) causess same functions to return '-1'
# (invalid multibyte sequence).
