Accents stored in Redis not being readable

Question

Working with Redis 2.10 using redis-cli on Linux, I am faced with a problem regarding accents.

If I execute the command :

set "string" "à"

I get \xc3\xa0, it seems each converted accent begin with \xc3.

How do I get my original string back?

OK I checked all my previous questions and it's effectively an UTF8 problem... — kozher, Jul 18 '11 at 10:36
It's usually not much of a problem, though. Do you absolutely have to use a 1-byte-per-char encoding? — Frédéric Hamidi, Jul 18 '11 at 10:39
@kozher did you find out how to read those string back with the accents ? — Luc, Jan 11 '12 at 14:34

Try using

redis-cli --raw

It solved problem for me.

Unfortunately this only works within the CLI, but not if you directly run the command all in one line (such as: redis-cli --raw HGETALL myHashKey > mqResult.txt). – Austin Salgat Nov 17 '17 at 02:19

"\xc3\xa0" is just Unicode "à" in UTF-8 encoding. Just decode the string and you're done...

You need to spec the version of Redis and more importantly the client you are using.

If you are using a telnet client, the problem may be your client. Redis supports arbitrary bytes for values and UTF-8 is not a problem at all (if your client is properly converting the entered glyphs to the associated byte sequence.)
