Description

Replaces unicode quotation marks with ASCII quotation marks.

For code examples, this fixes HCL decoding errors that would otherwise be raised when attempting to read the file.

Testing & Reproduction steps

1. Create a configuration entry that contains unicode quotation marks.

   # proxy-defaults-with-unicode-quotes.hcl
   Kind = “proxy-defaults”
   Name = "global"
   Config = {
     envoy_dogstatsd_url = "udp://127.0.0.1:8125"
   }

2. Attempt to save the configuration entry.

   $ consul config write proxy-defaults-with-unicode-quotes.hcl
   Failed to decode config entry input: Failed to decode config entry input: At 1:15: illegal char
   

The config entry fails to be decoded due to the unsupported unicode character.

Below is the behavior with the unicode quotes removed.

1. Create a configuration entry with only ASCII quotation marks.

   # proxy-defaults-with-ascii-quotes.hcl
   Kind = "proxy-defaults"
   Name = "global"
   Config = {
     envoy_dogstatsd_url = "udp://127.0.0.1:8125"
   }

2. Attempt to write the configuration entry.

   $ consul config write proxy-defaults-with-ascii-quotes.hcl                                                                                         
   Config entry written: proxy-defaults/global
