I am having the same error after upgrading to 3.5.2a4.
The error is reproducible when building espurna 1.12.1 (repo at GitHub - xoseperez/espurna: Home automation firmware for ESP8266-based devices)

================================== [ERROR] Took 66.00 seconds ==================================
OS is Ubuntu 16.04.3, updated today.
I checked the SCons mailing list[1] and there seems to be something broken in SCons 3.0.1 leading to a similar error in a different case.
Perhaps it would be possible to downgrade tool-scons to something before 3.30001.0, thus avoiding the breakage? Alas, I could not find an option or parameter in the pio documentation, allowing downgrade of a dependency package.
Any ideas?
I tried to downgrade to 3.20501.2 by putting "tool-scons": ">=3.20000.0,<3.30000.0" in penv/lib/python2.7/site-packages/platformio/managers/core.py
Apparently there are features missing in the older version of tool-scons
AttributeError: 'module' object has no attribute 'CConditionalScanner':
So, downgrading is not an option.
At first glance I am not quite sure where the data in env.SConscript("$BUILD_SCRIPT") originates (penv/lib/python2.7/site-packages/platformio/builder/main.py line 158)
Downgrading is the easiest solution
$ . ./.platformio/penv/bin/activate
$ pip install platformio==3.5.1
$ cd PIO/espurna
$ pio run -e itead-s20 -v

resulting in a good compile and working firmware image.
Thanks byteborg for the work around. I thought I was the only one in this situation and wasted a good hour searching for the source of the problem.
Because I’m not very familliar with platformio, I just replaced all the unicode characters with ascii ones.
Your work around is better though 
Could you try the latest PIO Core? pio upgrade —dev. Does it work now?
Hi @ivankravets. I have run the upgrade. The version shown now is 3.5.2a5. Compilation seems to be working even when I add non-ascii characters like “é”. Thanks.
