[code=32001:class=dump-unit:scope=internal:level=high] mydumper runs with error: exit status 1. option parsing failed: Invalid byte sequence in conversion input, try --help
请参考帖子先查下，多谢
系统中有中文的表名，task.yaml中需要怎么配置？
如果存在表名为中文，在DM中该如何配置？（整个库导入到TiDB）
1.请问你的 tidb 和 dm 版本是多少？ 2. 麻烦上传 dm-worker 日志，多谢。
日志中有句：“Tables needed to dump are not given, now we will start to generate table list that mydumper needs to dump through black-white list from given fromDB”
你好，
此日志信息为 task 中 mydumper 模块没有 table list，所以通过黑白名单进行配置，预期。
请反馈下 query-status 完整文本信息。看下同步状态，对于中文表名，线上规范不建议这样做，建议更改，尝试通过 mydumper -x 匹配看是否能解决，可以单独写 mydumper 的备份语句进行测试，否则只能修改表名来进行同步。
改成这个配置后报了另外一个错误：

我看了一下mydumper输出的文件，kiddo-schema-create.sql中只有一句：CREATE DATABASE kiddo /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci */;
metadata内容为： Started dump at: 2020-06-10 15:54:50 SHOW MASTER STATUS: Log: mysql-bin.006838 Pos: 677292386 GTID:
Finished dump at: 2020-06-10 15:54:50
把task.yaml中的extra-args改为"–regex ‘^(kiddo\.)’ --no-locks"就正常了~~开始导了，看看后面还会出什么问题~
