set s "é é é"

set sb [new_CkStringBuilder]

CkStringBuilder_Append $sb $s

# The string now contains: "é é é"

# If encoded to hex using the iso-8859-1 charset, 
# each é char is represented in 1 byte.
# Output: E920E920E9
puts [CkStringBuilder_getEncoded $sb hex iso-8859-1]

# If encoded to hex using the utf-8 charset, 
# each é char is represented in 2 bytes.
# Output: C3A920C3A920C3A9

# Here's utf-16
# Output: E9002000E9002000E900
