The method receives a first string S=s1 s2 . . . sn and a second string T=t1 t2 . . . tm, where s1, s2, . . . , sn and t1, t2, . . . , tm are Unicode characters. The method computes a first string weight for the first string S according to a weight function ƒ. When S consists of ASCII characters, ƒ(S)=S. When S consists of ASCII characters and some accented ASCII characters that are replaceable by ASCII characters, ƒ(S)=g(s1) g(s2) . . . g(sn), where g(si)=si when si is an ASCII character and g(si)=si′ when si is an accented ASCII character that is replaceable by the corresponding ASCII character si′. When S includes one or more non-replaceable non-ASCII characters, the first string weight concatenates an ASCII weight prefix ƒA (S) and a Unicode weight suffix ƒU(S). The method also computes a second string weight for the second text string T. Equality of the strings is tested using the string weights."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hybrid comparison for unicode text strings consisting primarily of ASCII characters","description":"A method compares text strings having Unicode encoding.
