String Operations
Mathematica incorporates the latest highly efficient algorithms to allow operations on strings with millions of elements, all making use of Mathematica's unique symbolic string patterns.
StringJoin join strings together
StringSplit split strings at whitespace, or any specified pattern
    
StringLength length of a string (in Unicode characters)
StringTrim trim whitespace etc. from strings
StringPosition find positions of substrings or string patterns
StringReplacePart replace substrings at specified positions
StringReverse reverse the characters in a string
    
StringReplace make replacements for substrings or string patterns
StringCases give all cases of string patterns in a string
StringCount count occurrences of a string pattern
    
Characters break a string into a list of characters
Hash compute hash codes for a string
ImportString, ExportString translate between many string formats
    
StringToStream set up a string to be read sequentially
