As of my last update in April 2023, there is no widely recognized or documented font named "K5" attributed to Rodrigo Fuenzalida in the mainstream design or typography communities. It's possible that the font you're asking about is a specialized or custom design that hasn't reached a broad audience or is known under a different name in public repositories and design platforms.

However, if we were to envision what a font named "K5" by a designer like Rodrigo Fuenzalida might entail, considering a speculative approach based on typical design philosophies and practices, we could imagine a few characteristics. Given Rodrigo Fuenzalida's background and potential design ethos, "K5" might embody qualities of innovation, functionality, and aesthetic appeal.

A speculative envisioning of "K5" might suggest a font that balances modernity with versatility, possibly offering a clean, geometric structure suitable for both digital and print mediums. Its design could prioritize readability while incorporating unique character details to set it apart from other typefaces. For example, "K5" could feature distinctive letterforms, such as a uniquely designed "k" or a numeral "5" with an innovative twist, serving as the font's signature elements.

The font might be designed with adaptability in mind, including a range of weights from light to bold, enabling it to function in various contexts—from headline text to body copy. The inclusion of italics, along with an extensive character set supporting multiple languages and special glyphs, could make "K5" a comprehensive choice for global design projects.

In an era where branding and digital presence are paramount, a font like "K5," conceptualized by a designer with a forward-thinking approach, could cater to both contemporary and futuristic design projects. It might be well-suited for tech companies, startups, and creative agencies looking to distinguish their identity with a fresh, original typeface.

Without specific information on a font named "K5" by Rodrigo Fuenzalida, this description remains a creative hypothesis inspired by the trends and necessities of contemporary type design.
