 *
**  This function used for translations HTML special fields inside tags
**  (ALT=, VALUE=, etc.) from charset `cs_from' to charset `cs_to'.
**  It also unescapes non-ASCII characters from URL (#fragments !)
**  if st_URL is active.
**
**  If `do_ent' is YES, it converts named entities
**  and numeric character references (NCRs) to their `cs_to' replacements.
**
**  Named entities converted to unicodes.  NCRs (unicodes) converted
**  by UCdomap.c chartrans functions.
**  ???NCRs with values in the ISO-8859-1 range 160-255 may be converted
**  to their HTML entity names (via old-style entities) and then translated
**  according to the LYCharSets.c array for `cs_out'???.
**
**  Some characters (see descriptions in `put_special_unicodes' from SGML.c)
**  translated in relation with the state of boolean variables
**  `use_lynx_specials', `plain_space' and `hidden'.  It is not clear yet:
**
**  If plain_space is TRUE, nbsp (160) will be treated as an ASCII
**  space (32).  If hidden is TRUE, entities will be translated
**  (if `do_ent' is YES) but escape sequences will be passed unaltered.
**  If `hidden' is FALSE, some characters are converted to Lynx special
**  codes (see `put_special_unicodes') or ASCII space if `plain_space'
**  applies).  @@ is `use_lynx_specials' needed, does it have any effect? @@
**  If `use_lynx_specials' is YES, translate byte values 160 and 173
**  meaning U+00A0 and U+00AD given as or converted from raw char input
**  are converted to HT_NON_BREAK_SPACE and LY_SOFT_HYPHEN, respectively
**  (unless input and output charset are both iso-8859-1, for compatibility
**  with previous usage in HTML.c) even if `hidden' or `plain_space' is set.
**
**  If `Back' is YES, the reverse is done instead i.e., Lynx special codes
**  in the input are translated back to character values.
**
**  If `Back' is YES, an attempt is made to use UCReverseTransChar() for
**  back translation which may be more efficient. (?)
**
**  If `stype' is st_URL, non-ASCII characters are URL-encoded instead.
**  The sequence of bytes being URL-encoded is the raw input character if
**  we couldn't translate it from `cs_in' (CJK etc.); otherwise it is the
**  UTF-8 representation if either `cs_to' requires this or if the
**  character's Unicode value is > 255, otherwise it should be the iso-8859-1
**  representation.
**  No general URL-encoding occurs for displayable ASCII characters and
**  spaces and some C0 controls valid in HTML (LF, TAB), it is expected
**  that other functions will take care of that as appropriate.
**
**  Escape characters (0x1B, '\033') are
**  - URL-encoded	if `stype'  is st_URL,	 otherwise
**  - dropped		if `stype'  is st_other, otherwise (i.e., st_HTML)
**  - passed		if `hidden' is TRUE or HTCJK is set, otherwise
**  - dropped.
**
**  (If `stype' is st_URL or st_other most of the parameters really predefined:
**  cs_from=cs_to, use_lynx_specials=plain_space=NO, and hidden=YES)
**
**
**  Returns pointer to the char** passed in
**		 if string translated or translation unnecessary,
**	    NULL otherwise
**		 (in which case something probably went wrong.)
