It replaces unprintable characters (other than \s-1CR, LF\s0) with '.'. .SH "NOTES" .IX Header "NOTES" \&\fBASN1_STRING_print()\fR is a legacy function which should be avoided in new applications. .PP Although there are a large number of options frequently \fB\s-1ASN1_STRFLGS_RFC2253\s0\fR is suitable, or on \s-1UTF8\s0 terminals \fB\s-1ASN1_STRFLGS_RFC2253 &\s0 ~ASN1_STRFLGS_ESC_MSB\fR. .PP The complete set of supported options for \fBflags\fR is listed below. .PP Various characters can be escaped. If \fB\s-1ASN1_STRFLGS_ESC_2253\s0\fR is set the characters determined by \s-1RFC2253\s0 are escaped. If \fB\s-1ASN1_STRFLGS_ESC_CTRL\s0\fR is set control characters are escaped. If \fB\s-1ASN1_STRFLGS_ESC_MSB\s0\fR is set characters with the \&\s-1MSB\s0 set are escaped: this option should \fBnot\fR be used if the terminal correctly interprets \s-1UTF8\s0 sequences. .PP Escaping takes several forms. .PP If the character being escaped is a 16 bit character then the form \*(L"\eUXXXX\*(R" is used using exactly four characters for the hex representation. If it is 32 bits then \&\*(L"\eWXXXXXXXX\*(R" is used using eight characters of its hex representation. These forms will only be used if \s-1UTF8\s0 conversion is not set (see below). .PP Printable characters are normally escaped using the backslash '\e' character. If \&\fB\s-1ASN1_STRFLGS_ESC_QUOTE\s0\fR is set then the whole string is instead surrounded by double quote characters: this is arguably more readable than the backslash notation. Other characters use the \*(L"\eXX\*(R" using exactly two characters of the hex representation. .PP If \fB\s-1ASN1_STRFLGS_UTF8_CONVERT\s0\fR is set then characters are converted to \s-1UTF8\s0 format first. If the terminal supports the display of \s-1UTF8\s0 sequences then this option will correctly display multi byte characters. .PP If \fB\s-1ASN1_STRFLGS_IGNORE_TYPE\s0\fR is set then the string type is not interpreted at all: everything is assumed to be one byte per character. This is primarily for debugging purposes and can result in confusing output in multi character strings. .PP If \fB\s-1ASN1_STRFLGS_SHOW_TYPE\s0\fR is set then the string type itself is printed out before its value (for example \*(L"\s-1BMPSTRING\*(R"\s0), this actually uses \fBASN1_tag2str()\fR. .PP The content of a string instead of being interpreted can be \*(L"dumped\*(R": this just outputs the value of the string using the form #XXXX using hex format for each octet. .PP If \fB\s-1ASN1_STRFLGS_DUMP_ALL\s0\fR is set then any type is dumped. .PP Normally non character string types (such as \s-1OCTET STRING\s0) are assumed to be one byte per character, if \fB\s-1ASN1_STRFLGS_DUMP_UNKNOWN\s0\fR is set then they will be dumped instead. .PP When a type is dumped normally just the content octets are printed, if \&\fB\s-1ASN1_STRFLGS_DUMP_DER\s0\fR is set then the complete encoding is dumped instead (including tag and length octets). .PP \&\fB\s-1ASN1_STRFLGS_RFC2253\s0\fR includes all the flags required by \s-1RFC2253.\s0 It is equivalent to: \s-1ASN1_STRFLGS_ESC_2253\s0 | \s-1ASN1_STRFLGS_ESC_CTRL\s0 | \s-1ASN1_STRFLGS_ESC_MSB\s0 | \s-1ASN1_STRFLGS_UTF8_CONVERT\s0 | \s-1ASN1_STRFLGS_DUMP_UNKNOWN ASN1_STRFLGS_DUMP_DER\s0 .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBX509_NAME_print_ex\fR\|(3), \&\fBASN1_tag2str\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" \&\s-1TBA\s0
