Default language breaks non-ascii and special characters

[ahyangyi]

Hi,

I noticed that non-ascii characters and special characters (such as {SILVER}) don't work for the default language file, no matter what language it is.

For example, if I have Chinese and English language files, if I set Chinese to the default, the Chinese strings will be broken; and vice versa.

By "broken" I mean that all non-ascii characters and special characters are shown escaped.

A minimal example:

#!/usr/bin/env python
import grf

def get_string_manager():
    s = grf.StringManager()
    s.import_lang_dir("lil/lang", default_lang_file="english-uk.lng")

    return s

def gen():
    s = get_string_manager()
    g = grf.NewGRF(
        grfid=b"MNMM",
        name=s["STR_GRF_NAME"],
        description="",
        strings=s,
    )

    g.write("minimum.grf")

if __name__ == "__main__":
    gen()

then the lang files:

lang/chinese.lng

##grflangid 0x56
STR_GRF_NAME                    :最{WHITE}小{RED}复{GOLD}现

lang/english-uk.lng

##grflangid 0x01
STR_GRF_NAME                    :Minimal {WHITE}Re{RED}producible {GOLD}Example

In this case the Chinese works but the English (UK) breaks because the latter is the default.

The "default language" strings are in Action 8, the other strings in Action 14. Perhaps this is the the reason of the difference...

Oh, I think I found it: the call to __str__ drops the special symbols,

Or, perhaps I should say that it didn't call grf_compile_string and left the escape strings there.
