require 'chilkat'

s = "é é é"

sb = Chilkat::CkStringBuilder.new()

sb.Append(s)
sb.EntityDecode()

# The string now contains: "é é é"
print sb.getAsString() + "\n";

# If encoded to hex using the iso-8859-1 charset, 
# each é char is represented in 1 byte.
# Output: E920E920E9
print sb.getEncoded("hex","iso-8859-1") + "\n";

# If encoded to hex using the utf-8 charset, 
# each é char is represented in 2 bytes.
# Output: C3A920C3A920C3A9
print sb.getEncoded("hex","utf-8") + "\n";

# Here's utf-16
# Output: E9002000E9002000E900
print sb.getEncoded("hex","utf-16") + "\n";

# utf-32
# Output: E900000020000000E900000020000000E9000000
print sb.getEncoded("hex","utf-32") + "\n";
