I recently noticed that including this API34+ unicode category, even though I guard with an API level check:

"""\p{InCJK_UNIFIED_IDEOGRAPHS_EXTENSION_H}""".toRegex()

breaks my Compose preview. Is there a way to programmatically check I’m in Compose preview?

Note: I’m not using this directly in the composable, so didn’t get any kind of compile time error/warning (though you do get this when using directly)

LocalInspectionMode.current

Thanks, but I’m not in a composable context either. This code is executed as part of some class initialization

Can you not use that class in Preview? Or change its init based on it?
No idea what the underlying issue is.

If you just paste that code into a Preview you get “unknown character category” message and the category is highlighted in red, and the preview breaks. I don’t know if it’s just that the compose preview parser is using some pre 34 API level
