=head1 NAME

i2s_ASN1_UTF8STRING,
s2i_ASN1_UTF8STRING
- convert objects from/to ASN.1/string representation

=head1 SYNOPSIS

 #include "crypto/x509v3.h"

 char *i2s_ASN1_UTF8STRING(X509V3_EXT_METHOD *method,
                           ASN1_UTF8STRING *utf8);
 ASN1_UTF8STRING *s2i_ASN1_UTF8STRING(X509V3_EXT_METHOD *method,
                                      X509V3_CTX *ctx, const char *str);

=head1 DESCRIPTION

These functions convert OpenSSL objects to and from their ASN.1/string
representation. This function is used for B<X509v3> extentions.

=head1 NOTES

The letters B<i> and B<s> in i2s_ASN1_UTF8STRING() stand for
"internal" (that is, an internal C structure) and string respectively.
So B<i2s_ASN1_UTF8STRING>() converts from internal to string.

=head1 RETURN VALUES

B<s2i_ASN1_UTF8STRING>() return a valid
B<ASN1_UTF8STRING> structure or NULL if an error occurs.

B<i2s_ASN1_UTF8STRING>() returns the pointer to a UTF-8 string
or NULL if an error occurs.
