René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Non english characters not deserialized successfully","articleBody":"When some non-english characters are serialized and deserialized back, the output is not as expected. All those non-english characters are lost and replaced with some generic symbols. But this is not the case with all msgpack and Java versions.\nThe following piece of code behaves differently accross jackson-dataformat-msgpack and Java versions.\n```\nObjectMapper objectMapper = new ObjectMapper(new MessagePackFactory());\nString inputStr = \"çÇğĞıİöÖşŞüÜ\";\nbyte[] arr = objectMapper.writeValueAsBytes(inputStr);\nString outputStr = objectMapper.readValue(arr, String.class);\nSystem.out.println(outputStr);\n```\nThe case was tested with Turkish characters in Java 8 and Java 21, with jackson-dataformat-msgpack versions 0.9.8 to 0.9.10.\nHere are the results:\n- In Java 8, jackson-dataformat-msgpack versions 0.9.8, 0.9.9 and 0.9.10 all give the correct result, ie. outputStr=inputStr (çÇğĞıİöÖşŞüÜ)\n- In java 21, jackson-dataformat-msgpack version 0.9.8 give the correct result, ie. outputStr=inputStr (çÇğĞıİöÖşŞüÜ)\n- In java 21, jackson-dataformat-msgpack versions 0.9.9 and 0.9.10 give the wrong result, ie. outputStr is something like çÇğÄ?ıİöÖşÅ?üÜ\n\nAnything I'm missing here, like some new settings, or is it a bug?","author":{"url":"https://github.com/tronurg","@type":"Person","name":"tronurg"},"datePublished":"2025-08-05T18:29:19.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/908/msgpack-java/issues/908"}
