Substitute( s, from, to )
SubstituteAll( s, from, to )
The Substitute(s, from, to) function replaces the first occurrence of the string from in the string s by the string to, and returns the resulting string. The original string s is not modified. Strings are immutable in Maple.
The SubstituteAll(s, from, to) function replaces all occurrences of from in s by to, and returns the resulting string. The original string s is not modified.
Only the first of overlapping occurrences of from in s is subject to replacement by to.
All of the StringTools package commands treat strings as (null-terminated) sequences of 8-bit (ASCII) characters. Thus, there is no support for multibyte character encodings, such as unicode encodings.
