String.Find differs from its Lua equivalent

[mezzodrinker]

Take the following script:

String.Find('This is a test.', 'i')

This should, if String.Find behaved like its Lua equivalent, return 3, 3, as the indexes are 1-based and the begin and end positions are both inclusive. However, String.Find returns 2, 3 as 0-based indexes, with the end position being exclusive.

The behaviour should be adjusted to be equivalent to Lua's string.find.

Don’t forget to update the wiki page once this issue has been resolved.

In addition to the above, String.Find uses Java’s regular expression syntax, whereas Lua’s patterns work differently.
