  25      -.sp
  26   31  .LP
  27   32  The \fBbtowc()\fR and \fBbtowc_l\fR()functions determines whether
  28   33  \fIc\fR constitutes a valid (one-byte) character in the initial shift
  29   34  state.
  30      -.sp
  31   35  .LP
  32      -The behavior of \fBbtowc\fR is affected by the \fBLC_CTYPE\fR category of the
  33      -current locale.  See \fBenviron\fR(5). The function \fBbtowc_l\fR does
  34      -not use the current locale, and instead operates on the locale \fIloc\fR
  35      -provided to the function, obtained through a call to
  36      -\fBnewlocale\fR(3C).
       36 +The behavior of \fBbtowc()\fR is affected by the \fBLC_CTYPE\fR category of the
       37 +current locale.  See \fBenviron\fR(5). The function \fBbtowc_l()\fR does
       38 +not use the current locale, and instead operates on the locale 
       39 +specified by \fIloc\fR.
  37   40  .SH RETURN VALUES
  38      -.sp
  39   41  .LP
  40   42  The \fBbtowc()\fR function returns \fBWEOF\fR if \fIc\fR has the value
  41   43  \fBEOF\fR or if  \fB(unsigned char)\fR\fIc\fR does not constitute a valid
  42   44  (one-byte) character in the initial shift state.  Otherwise, it returns the
  43   45  wide-character representation of that character.
