Patch notes:
- Attempted to fix a bug that makes the game break for people who have French names (I'm dead serious. More details below)
- Upgraded the engine version. This will hopefully help fix rare crash bugs
- Made it easier for hackers to write an autosplitter for Outcore.
French names bug
For some players, when Lumi asks the player to open a folder such as "Documents" or "Downloads", she fails to recognize the folders being opened. She simply stands there doing nothing, leaving players confused.
After receiving several "Player.log" files from players who encountered this bug I noticed something common: They all appear to have French Windows usernames.
"Doctor Shinobi, you little clown, did you just make a racist bug?"
Woah woah woah hold on, I can explain everything.
I suddenly remembered it's not just French! This also used to happen with... Turkish people!
"Great, now you're racist against the Turkish people too"
Or am I...??? I'm going to prove my innocence by presenting the technical details behind this bug.
Why this bug happens
Aright nerds, let's dive in.
I previously publicly mentioned that when you play Outcore you actually run 2 apps at the same time:
- Outcore, the game.
- A special invisible program I wrote called "WindowsUtility", which in short we'll call WU.
I wrote WU to assist Outcore with interacting with your Windows OS. For example, you know how at the beginning of the game Lumi's glitch blob points you to her first file? It knows its position on the screen thanks to WU.
Outcore and WU communicate with each other like a server and a client, except they are both on your computer. The bug occurs inside WU, way before the information is communicated to Outcore.
When Lumi asks you to open a folder, she instructs WU to check the address of any folder that you open.
Let's say Lumi asks the player to open the Downloads folder. Outcore will send a love letter to WU saying "Hey WU, my brother which I dearly love. please let me know when a folder with the address 'C:\Users\DoctorShinobi\Downloads' is opened and focused"
WU will then check the address of every folder that is opened. If it's equal to C:\Users\DoctorShinobi\Downloads then WU will respond to Outcore with this letter:
"Greetings, Outcore, my twin sibling which I definitely do not hate for being more popular than me, the folder you requested has been opened by the master of this computer".
Outcore will then notify Lumi about this exciting news. She will change animation and probably say something like "wow look at this, it's my file, yeaaahh let's gooo".
BUT
French names, amright? In French you have these accented letters such as "é, è, ê, ô, û, à, É, È, Ê, Ô, Û, À, ï, Ï, ë, Ë", and more!
Let's imagine this hypothetical universe in which I am French. Lumi would ask WU to monitor this folder:
C:\Users\DôctôrShinôbï\Downloads
When the folder is opened and WU checks its address, it's actually going to read something that looks like this:
C%3A%5CUsers%5CD%F4ct%F4rShin%F4b%EF%5CDownloads
Weird, right? I'll tell you why it looks like this.
If you ever looked at a website's address, you'd often see symbols like this. I don't know what's up with URLs but they don't really support all types of characters. To work around that, browsers/websites encode the URL addresses, which is called "escaping".
When you escape a URL, you're replacing all special characters with regular ones that represent them.
For example, "/" is replaced with "%5C". "ô" is replaced with "%F4", and so on...
Then after the escaped URL is transferred somewhere, the receiving end can unescape it to get the original text.
The folder URL that WU reads is escaped. to Unescape it, I use a C# function called "Uri.UnescapeDataString". It works well most of the time, but it fails to unescape accented letters for some reason.
The somewhat bizarre solution is to manually unescape the URLs myself. This is something I've done in the past with accented Turkish letters, but had to extend with more letters for the French ones:
Can't say I'm super happy with this since I keep discovering new letters that need to be added. But at least it should be good enough for most cases.
If you still encounter this issue then let me know in the Steam forums on the game's Discord server
