PUT /reactions/.../@me returns 404 for certain emojis

[xgedev]

Hello,
I discovered that nirn-proxy does not allow you to add certain emojis as reactions to messages.

Emojis not working (the only ones that were discovered yet):

• #️⃣
• *️⃣

Error thrown by discord.js (only when the api url is nirn-proxy, without it it works fine):
DiscordAPIError[0]: 404: Not Found {
requestBody: { files: undefined, json: undefined },
rawError: { message: '404: Not Found', code: 0 },
code: 0,
status: 404,
method: 'PUT',
url: 'http://localhost:3000/api/v10/channels/.../messages/.../reactions/%23%EF%B8%8F%E2%83%A3/@me'
}
