Support UTF-8 Characters in get_from_vdf_file

[pallen0304]

Background:

Patcher gets stuck when attempting to patch executable. This is caused by some games having UTF-8 characters (e.g. Japanese characters) in the appmanifest .acf files 'name' property. I discovered this as the cause after running the patcher with debug enabled.

Example:

Log hangs with final statement:
"[DEBUG] From appmanifest_174531.acf getting values of appid" is the last item logged, which correlates to a file with:
Name property of appmanifest_174531.acf:
"name" "與經紀人戀愛是絕對禁止！"

Related Code:

I'm not certain of how to fix this in Python, but the logs narrow it down to be within this code in steam_helper.py.

<Perma-link to code in v1.1.0-pre tagged commit>

vdf_fh = vdf.load(open(vdf_file))
values_out = self.recursive_dict_find_value(vdf_fh, key, stop_on_find)

Workaround

I was able to work around this issue by editing all the .acf files containing UTF8 characters and changing the name property value to use ASCII characters only

Hey @pallen0304

Thank you so much for the wonderfully detailed report!

I'll look into this, need to do some tests then on it, but good that you found it.

I was about to post an issue on my patcher getting stuck as well, but I think this might be the issue as I have games with Chinese characters in their title. Glad you are looking into it
