windows: Unhandled exception / No such file or directory: 'merged.ttf'

Windows 11 Pro build 22581, TwitterColorEmoji-SVGinOT-Win-13.1.0.zip

I have a small brain so I'm not too sure how to fix this:

Checking if Segoe UI Symbol is installed.
Checking if prerequisites are installed.
Ensuring the latest FontTools is installed.

Any help would be very much appreciated!

Seems like the merging process did not end well (don't know why :P). But I can help. Do you want to replace completely the Windows emoji font with the Twitter emoji font? If so I can edit the font manually so that when installed it will replace the Windows emoji font.

Two issues here resolve.

1. These windows scripts need to hard crash at the first hint of failure

2. Original failing error is:

   ERROR: An exception occurred during the decompilation of the 'SVG '
   UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf9 in position 1: invalid start byte`

   This may be a bug in fontTools.

I don't have a Windows 11 install, so this issue needs help from the community. It would be great to see both of these issues resolved.

2. This may be a bug in fontTools.

I came across this issue after running in to the same error trying to merge SEGUISYM.TTF (From Win10) with a modified font from another project while on Linux Mint so it may very well may be a bug with fontTools and outside the scope of this project. Even running just pyftmerge -h results in FileNotFoundError: [Errno 2] No such file or directory: "-h"

Hi all,

I'm very sorry for my late response to this issue, despite being the one to originally post it! Honestly, it completely slipped my mind, and I can't quite remember what I was trying to do.

Seems like the merging process did not end well (don't know why :P). But I can help. Do you want to replace completely the Windows emoji font with the Twitter emoji font? If so I can edit the font manually so that when installed it will replace the Windows emoji font.

Thank you so much for this kind offer! I believe you're right and that I was trying to replace the Windows emojis with Twitter ones. Going through the process of installing now, it seemed to have completed normally without blaring warnings at me, but I can't recall if I originally posted this pre- or post-PC upgrade; I don't know what changed to make it work this time.

The only issue now is that despite completing the installation through "Standard Install" and "Replace the default Windows emoji fonts", as well as Chocolatey just to be sure, my emojis still aren't in the Twitter style. I restarted Firefox, Windows, and also scrolled through the emoji list in the Windows Key + . shortcut to confirm. Maybe I misunderstood what the scripts are for or missed a step somewhere? Either way, it's not quite the same issue as originally posted here.

Cheers.
