# Ruby (computer programming) — Software Engineer

As a Software Engineer proficient in Ruby, it's not *just* about knowing the syntax. Daily work revolves around building web applications – often using the Rails framework – or scripting automation tasks. You’ll spend time writing clean, maintainable code to handle requests, interact with databases (PostgreSQL is common), and implement business logic. Expect a lot of testing: RSpec & Capybara are standard for unit/integration tests.  You'll also be reading and refactoring existing Ruby codebases, so understanding design patterns and SOLID principles *within* the Ruby ecosystem is crucial.

## Praxiswissen (Stack Exchange, CC-BY-SA 4.0)

**The asker's MySQL database is configured for Latin-1, causing errors when users input UTF-8 characters. Their boss wants to strip these 'bad characters', but the asker believes switching to UTF-8 would be a better solution and questions if there are valid reasons to stay with Latin-1.**

Prioritize supporting the full range of Unicode characters (using UTF-8) rather than restricting input, as modern applications should accommodate diverse user content. While Unicode introduces complexity, limiting character sets hinders functionality beyond just internationalization – even basic English typography can be affected. Concerns about 'bad' characters are often based on misunderstandings; normalization techniques and careful handling of control characters can mitigate potential issues with searching or data integrity.
