**
**    unicode-glob     The VALUE is a comma or newline-separated list of
**     (versionable)   GLOB patterns of files that should not produce a Unicode
**                     warning.  Set to "*" to disable Unicode checking.
**
**    web-browser      A shell command used to launch your preferred
