This commit fixes two test cases:
- Whitedlisted chars (success), where the config and expected jsons are
misconfigured;
- Whitelisted chars (invalid). This test was removed. Since stedrr is
preserved with execution in sadnbox, and while stderr contains
"original" bad non-ASCII characters that are filtered, this creates a
paradox. Thus, the test case is removed for now, pending investigation
into this matter.
This commit brings support of whitelisted characters during repo
healthcheck/non-ascii file check. Supported by an extra switch to
`repo-health-checker`, `-whitelistedChars`. The argument takes a
comma-separated list of non-ASCII characters and ignores them during
repo healthcheck. Illegal cmdline input is logged by the logger.
