I need your help to create a regular expression which supports the following quoted string for informix database
quoted-string = (qdtext / quoted-pair )
qdtext = / %x21 / %x23-5B / %x5D-7D / UTF8-NONASCII
The backslash character ("\") MAY be used as a single-character
quoting mechanism only within quoted-string and comment constructs.
Unlike HTTP/1.1, the characters CR and LF cannot be escaped by this
mechanism to avoid conflict with line folding and header separation.
quoted-pair = "\" (%x00-09 / %x0B-0C
