File encoding in stats

How do I get my analog stats to keep non-Roman search text as entered? If someone looks for


I’d like the stats to say so, instead of changing it into


(It’s reinterpreting UTF-8 as Latin-1, which here means breaking each three-byte character into three one-byte characters. But it isn’t necessary to understand that part if it’s not already familiar.)

Analog’s own information says to add the line SEARCHCHARCONVERT ON, and I found the plain-text file in the logs directory where it seems as if this line should be added… but it won’t let me touch the file. No explanation, just a popup that says I’m not allowed to do anything to it.
