\&\fBX509_NAME_get_text_by_NID()\fR and \fBX509_NAME_get_text_by_OBJ()\fR are
legacy functions which have various limitations which make them

be highly confusing if the target is a muticharacter string type
like a BMPString or a UTF8String.
.PP
For a more general solution \fBX509_NAME_get_index_by_NID()\fR or
\&\fBX509_NAME_get_index_by_OBJ()\fR should be used followed by
