UTF-8 vs ASCII for multilingual embedded systems

ASCII works well for basic English characters, but it becomes limiting when an application needs Hindi, Tamil, or other scripts. UTF-8 provides Unicode support while remaining compatible with ASCII for standard characters. How are others handling UTF-8 storage and rendering in resource-constrained embedded systems?

UTF-8 is definitely way to go.

But what means resource constrained? it depends. Today embedded MMI products have huge amounts of memory and fast CPUs.

To store long texts you can use common compression libraries, or use methods specific to your language.

Note that filename encoding in FatFs is completely different issue. To avoid conflicts with legacy filesystem drivers, consider using strictly ASCII or English filenames, and somehow map them to fully localized/globalized strings in your application (for example, via configuration files)

Seems like an AI post to me, along with the related. Generic question, almost nonsensical, tenuous link to STM32, thinly veiled username pointing to AI slop software of the same title.
