+=head1 NAME
+
+i2s_ASN1_UTF8STRING,
+s2i_ASN1_UTF8STRING,
+- convert objects from/to ASN.1/string representation
+
+=head1 SYNOPSIS
+
+=for openssl generic
+
+ 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 B<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.
