See glib/types.h:

typedef char   gchar;

In other words: "gchar" is just a Glib-specific alias for "char". There
is no need for a real conversion since their data format is identical.

What you should get when assigning a "char" with a "gchar" value (or
vice versa) is a compiler warning only. (Some compilers may be fussier
about it, however.) That's just because the names of the types of the
variables differ, while their contents don't. The resulting code would
work fine (though the warnings are ugly).

Use type casts to avoid warnings when assigning across different
variable types. I.e.:

char a;
gchar x;
x = (gchar) a;
