     These functions output an AAAASSSSNNNN1111_SSSSTTTTRRRRIIIINNNNGGGG structure. AAAASSSSNNNN1111_SSSSTTTTRRRRIIIINNNNGGGG
     is used to represent all the ASN1 string types.

     ASN1_STRING_print_ex() outputs ssssttttrrrr to oooouuuutttt, the format is
     determined by the options ffffllllaaaaggggssss. ASN1_STRING_print_ex_fp()
     is identical except it outputs to ffffpppp instead.

     ASN1_STRING_print() prints ssssttttrrrr to oooouuuutttt but using a different
     format to ASN1_STRING_print_ex(). It replaces unprintable
     characters (other than CR, LF) with '.'.

NNNNOOOOTTTTEEEESSSS
     ASN1_STRING_print() is a legacy function which should be
     avoided in new applications.

     Although there are a large number of options frequently
     AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_RRRRFFFFCCCC2222222255553333 is suitable, or on UTF8 terminals
     AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_RRRRFFFFCCCC2222222255553333 &&&& ~~~~AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_EEEESSSSCCCC_MMMMSSSSBBBB.

     The complete set of supported options for ffffllllaaaaggggssss is listed
     below.

     Various characters can be escaped. If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_EEEESSSSCCCC_2222222255553333
     is set the characters determined by RFC2253 are escaped. If
     AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_EEEESSSSCCCC_CCCCTTTTRRRRLLLL is set control characters are escaped.
     If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_EEEESSSSCCCC_MMMMSSSSBBBB is set characters with the MSB set
     are escaped: this option should nnnnooootttt be used if the terminal
     correctly interprets UTF8 sequences.

     Escaping takes several forms.

     If the character being escaped is a 16 bit character then
     the form "\UXXXX" is used using exactly four characters for
     the hex representation. If it is 32 bits then "\WXXXXXXXX"
     is used using eight characters of its hex representation.
     These forms will only be used if UTF8 conversion is not set
     (see below).

     Printable characters are normally escaped using the
     backslash '\' character. If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_EEEESSSSCCCC_QQQQUUUUOOOOTTTTEEEE 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 "\XX" using
     exactly two characters of the hex representation.

     If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_UUUUTTTTFFFF8888_CCCCOOOONNNNVVVVEEEERRRRTTTT is set then characters are
     converted to UTF8 format first. If the terminal supports the
     display of UTF8 sequences then this option will correctly
     display multi byte characters.

     If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_IIIIGGGGNNNNOOOORRRREEEE_TTTTYYYYPPPPEEEE 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.

     If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_SSSSHHHHOOOOWWWW_TTTTYYYYPPPPEEEE is set then the string type itself
     is printed out before its value (for example "BMPSTRING"),
     this actually uses ASN1_tag2str().

     The content of a string instead of being interpreted can be
     "dumped": this just outputs the value of the string using
     the form #XXXX using hex format for each octet.

     If AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_DDDDUUUUMMMMPPPP_AAAALLLLLLLL is set then any type is dumped.

     Normally non character string types (such as OCTET STRING)
     are assumed to be one byte per character, if
     AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_DDDDUUUUMMMMPPPP_UUUUNNNNKKKKNNNNOOOOWWWWNNNN is set then they will be dumped
     instead.

     When a type is dumped normally just the content octets are
     printed, if AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_DDDDUUUUMMMMPPPP_DDDDEEEERRRR is set then the complete
     encoding is dumped instead (including tag and length
     octets).

     AAAASSSSNNNN1111_SSSSTTTTRRRRFFFFLLLLGGGGSSSS_RRRRFFFFCCCC2222222255553333 includes all the flags required by
     RFC2253. It is equivalent to:
      ASN1_STRFLGS_ESC_2253 | ASN1_STRFLGS_ESC_CTRL |
     ASN1_STRFLGS_ESC_MSB |
      ASN1_STRFLGS_UTF8_CONVERT | ASN1_STRFLGS_DUMP_UNKNOWN
     ASN1_STRFLGS_DUMP_DER
