-utf8 option does not work

[espresso3389]

With vswhere 3.0.1+e2e4e03c65 bundled with VS2022 17.1.6, -utf8 option does not work correctly; even with the option, the command seems to run with the machine's locale. The code described here throws exception during parsing the output:

SyntaxError: Unexpected end of JSON input

Node.js v18.0.0

Thanks for reporting this. I was able to reproduce an issue - though not an exception from JSON.parse() on Node 16 - with vswhere 3.0.1 unless I change the console codepage to 65001, which shouldn't be necessary with this code snippet. With default US codepage 437 using vswhere 2.7.1 I do not see the replacement characters.
