fix(watermarker): off-by-one error in watermark extraction #11

Closed hnorkowski closed 3 months ago

hnorkowski commented 3 months ago

Description

Fixes an off-by-one error in the range used to extract the chars from a String containing a single watermark.
- The bug only surfaces when there are multiple successive spaces; otherwise only a text char is skipped that is not part of the watermark
Adds test cases that ensures that extracted watermarks are equal to the inserted watermark
