Getting this error when I try to build and include these packages in my project

byte index 129 is not a char boundary; it is inside '“' (bytes 128..131) of `[package]
name = "rust-opencv"
version = "0.1.0"
edition = "2021"

[dependencies]
opencv = "0.91.3"
cgmath = "0.18.0"
algebra = “0.32.5”`
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

This is my Cargo.toml file

[package]
name = "rust-opencv"
version = "0.1.0"
edition = "2021"

[dependencies]
opencv = "0.91.3"
cgmath = "0.18.0"
algebra = “0.32.5”
