If I understand your question correctly, yes, there are differences in keyword spacing between English-speaking countries and other countries.
For example, in English, keywords are usually separated by spaces, right?
While, let's say languages like Japanese, Korean, or Chinese don't use spaces in the same way.
Of course, there is also a difference that impacts how search engines work and indexes those keywords, so SEO strategies can vary quite a bit from one region to another.
Again, if I understand your question correctly, if not, please add more details.
