8424981: "Fix invalid read in quote_c_style_counted" introduced a test
that used "caractère spécial" as a directory name.
Git creates it as "caract\303\250re sp\303\251cial"
OS X stores it as "caracte\314\200re spe\314\201cial"
To work around this problem, use the already introduced $FN as the
directory name.
