I hope villager name support another language, not only English

You can configure the list of allowed characters inside the config. See the comments inside the default config (https://github.com/Shopkeepers/Shopkeepers-Wiki/wiki/Configuration#default-configuration) for the setting name-regex: There are some examples on how to configure this setting to allow non-latin characters to be used in shop names.

Try for example name-regex: "[\\p{L}0-9 ]{3,25}"
