python3-mutf8 1.0.6-1 (s390x binary) in ubuntu oracular

 This package contains simple pure-python as well as C encoders
 and decoders for the MUTF-8 character encoding.
 In most cases, it can also parse the even-rarer CESU-8.
 .
 These days, someone will most likely encounter MUTF-8
 when working on files or protocols related to the JVM.
 Strings in a Java .class file are encoded using MUTF-8,
 strings passed by the JNI,
 as well as strings exported by the object serializer.
 .
 This library was extracted from Lawu,
 a Python library for working with JVM class files.
