Subject: Update: The f_utf_is_* functions should be more specific on return state for F_failure.
X-Git-Tag: 0.5.10~154
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=1f593a0e49a696fe1768eb16fca610bef4cf2b8d;p=fll

Update: The f_utf_is_* functions should be more specific on return state for F_failure.

Rather than returning F_failure, return F_complete_not_utf.
