The compilation could not be completed

[CanNev]

Describe the bug The compilation could not be completed, The compilation process stops at one step and cannot continue

To Reproduce Possible cause of failure is Microsoft Windows system update I have reinstalled all related components,include PlatformIO and Python3.8 But the problem still exists

• Arduino IDE version: PlatformIO Core 4.3.3·Home 3.2.2
• STM32 core version: 6.1.0

Additional context My English is not very good, please forgive me if the description is not good

Its not a compile error, its a unicode parsing error inside platformio scripts (probably chinese language related), so you should open an issue there

And by the way, genericSTM32F103C8 uses another core by default

I confirm that the text encoding is UTF-8, not GBK Also on my own personal computer(use Linux), These problems will not occur the Linux language is English,not Chinese. So is it a Windows system, and the problem of Chinese encoding? In addition What does it mean of genericSTM32F103C8 uses another core by default ?

What does it mean of genericSTM32F103C8 uses another core by default ?

There are several arduino cores exist for stm32 mcus Platformio uses two of em, this one and libmaple based core, which core be used defined in the json file for each board

Hi @CanNev As @stas2z mentioned PIO uses this core https://github.com/rogerclarkmelbourne/Arduino_STM32 for the target you used. Moreover PIO is not supported here only Arduino IDE, you should request support here: https://github.com/platformio/platform-ststm32
