错误：'ascii'编解码器无法解码位置91中的字节0xe2：序数不在范围内（128）

Question

docker-compose build工作正常，但如果尝试使用docker-compose up，则会出现以下错误消息：

ERROR: for identityserver  'ascii' codec can't decode byte 0xe2 in position 91: ordinal not in range(128)
Traceback (most recent call last):
  File "docker-compose", line 3, in <module>

搬运工-compose.yml：

identityserver:
 build: ./IdentityServer
 dockerfile: ./dockerfile
 container_name: identityServer
 volumes:
   - ./:/app/
 environment:
  - ASPNETCORE_ENVIRONMET=Development
 ports:
  - "5000:5000"

dockerfile：
