Name: codepointOffset
Type: function
Syntax: codepointOffset(<stringToFind>, <stringToSearch> [, <codepointsToSkip>])
Summary:
Returns the number of codepoints between the beginning of a value and an
occurrence of a specified string.
Introduced: 7.0
OS: mac, windows, linux, ios, android
Platforms: desktop, server, mobile
Example:
codepointOffset(tCodePoint,"This is the string to search")
Parameters:
stringToFind (string):
stringToSearch (string):
codepointsToSkip:
The codepointsToSkip is a non-negative integer. If you don't specify how
many codepointsToSkip, the codepointOffset function does not skip any
codepoints.
Returns:
The <codepointOffset> function returns a non-negative integer.
Description:
Use the <codepointOffset> function to find which codepoint a string
occurs in.
The value returned by the <codepointOffset> function is the number of
the codepoint where the <stringToFind> appears in <stringToSearch>. If
the <stringToFind> is not in <stringToSearch>, the <codepointOffset>
function returns zero. If the <stringToFind> is more than one codepoint,
the <codepointOffset> function always returns zero, even if the
<stringToFind> appears in the <stringToSearch>.
If you specify how many <codepointsToSkip>, the <codepointOffset>
function skips the specified number of sentences in the
<stringToSearch>. The value returned is relative to this starting point
instead of the beginning of the <stringToSearch>.
