In that case I guess there isn't a problem.

I am a little concerned that unibyte locales use bytes whereas multibyte locales 
use characters for range expressions. As I understand it, this means Turkish 
range expressions are interpreted differently depending on whether the locale 
uses UTF-8 or ISO/IEC 8859-9. Is that really what Turkish-speakers want?

That being said, it doesn't matter all that much nowadays now that UTF-8 has 
taken over, so it's probably not worth much of our time to worry about this 
discrepancy. For what it's worth, 
https://w3techs.com/technologies/details/en-iso885909/all/all says that only 
0.06% of websites still use ISO/IEC 8859-9, down from 0.09% a year ago (and down 
from 0.7% in 2010, so this is a factor-of-10 decline in 8 years).
