Factorio Forums

Hi,

factorio 0.11.22 shall crash while it boots up before producing its log file.
This problem will occur when the system encoding is kCFStringEncodingMacJapanese. (also may occur at other encoding except kCFStringEncodingMacRoman. maybe)

I think the problem is easy to fix.
HTH,

Mac OSX 10.9.4

Any idea what does "system encoding" mean?

If it is an encoding throughout the entire system, it should take several hours to change.
If it doesn't do that, what the hell is it an encoding of?

An encoding throughout the entire system, that's right..
Wow you called the API, didn't you?

I forced CFStringGetCStringPtr to use kCFStringEncodingUTF8 and then told boost to use utf8_codecvt_facet to represent it properly, so that should work, if the CFString manages to convert itself to UTF-8. I unfortunately have no way of testing this and getting a Japanese OS X is no easy task, even having it as a VM would probably be difficult. I'll mark this as resolved and we'll have to see, if this actually works when 0.12 is released.
