String and Text Processing in Java on a Scale

Co-presented with Kyrylo Holodnov. A meetup repeat of the JEEConf 2019 talk at iHUB on Khreshchatyk: what we learned running Java string processing at Grammarly's scale — Java 11's reworked String, JVM string hacks worth keeping, fast regexes, the perils of emoji, and what the true length of a Java string actually is once other services see it.
