warning: Parent's environment is inaccessible, skipping term=parent checks.
warning: (shell) LANG: non-UTF8 locale "C"
warning: (term) LANG: non-UTF8 locale "C"

problem: Your current locale is using a legacy charset.
 * The incorrect variables are:
   - (term) LANG          (currently "C")
   - (shell) LANG         (currently "C")
 * Change your locales to their UTF-8 variants.

1 problems found. Here's a quick UTF-8 test for you:  --> â <--
 * a star             -- font and terminal are okay.
 * 3 question marks   -- your terminal does not correctly interpret UTF-8.
 * a box or rectangle -- UTF-8 works fine, but you need a better font.
 * empty area         -- you really need a better font or something.
