zrevrange() gives empty results

• Version: 5.0.3(Linux on Docker)
• Platform: Node.js v8.12.0 on Windows 10
• Description: zrevrange() returns [] even though on redis-cli it gives non-empty array as result.

let idList = await this.client.zrevrange(${this.exactStore}:${word}, 0, -1);

Output from Code:

console.log(ZREVRANGE ${this.exactStore}:${word} 0 -1); produces the following ZREVRANGE exactstore:rse:frank⁠ 0 -1 []

Output from Redis-Cli:

127.0.0.1:6379> ZREVRANGE exactstore:rse:frank 0 -1

1. “aG2_aHKvxFEzE9CeUlo_y”
2. “JHihXTds2T0cNnr4er0D1”

Please take a look at node_redis for the same issue in node_redis libary.

@luin Thanks for the important information. I got the commands back and is being executed on same db, but I found out that there’s a word joiner unicode character \xe2\x81\xa0 present in the strings which are actually present in the db. But there’s no extra unicode character in my string before I pass it to zrevrange().

@luin yes ofcourse, after identifying that an extra unicode character is present, I got the idea that it had nothing to do with neither redis client nor redis itself. I was asking that doubt in general.
