Handle non-ASCII characters

[ashley-evans]

Value Added

More accurate occurrence results

Description

Currently non-ASCII characters can be found by getKeyPhrases within find-keyphrases, however, countKeyPhrases is unable to then count the number of occurrences of that key phrase/word on the page.

Therefore, the occurrence counting functionality should be updated such that it can handle these characters.

Acceptance Criteria

AC01

• If a keyword/phrase has been found that includes non-ASCII characters then the countKeyPhrases function must be able to count the number of occurrences of that keyword/phrase

AC02

• The number of occurrences must be stored in dynamodb as before
