Please improve automatic generation of internal names from Japanese labels

When creating properties, entering labels in Japanese or using kanji results in the message “Could not generate an internal name for this label,” making it difficult to proceed with creation.

I would like valid internal names to be automatically generated even for Japanese labels, or for candidate internal names to be suggested. Additionally, if automatic generation fails, please display the reason and specific steps to resolve the issue on the error screen.

I would like the burden of manually devising and entering internal names one by one reduced when creating a large number of items in Japanese.
