Why is ↔ turned into ↔️?

On Anki for iOS, the note content ↔ (U+2194) ist turned into ↔️ automatically. Why and how do I get my text back? Thanks!

This is most likely due to iOS, not Anki. See this explanation.


On desktop, both symbols are displayed identically. To make this a bit clearer, I inspected the raw content of my clipboard and found the following:

  • the original only contains U+2194 (LEFT RIGHT ARROW)
  • the replacement contains both U+2194 and U+FE0F (VARIATION SELECTOR-16)

As to why something like this might happen, here’s an excerpt from the manual:

Text like á can be represented in multiple ways on a computer, such as using a specific code for that symbol, or by using a standard a and then another code for the accent on top. This causes problems when mixing input from different sources, or using different computers - if your computer handles keyboard input in one form, but the content is stored in a different form, it will not match when searching, even though the end result appears identical.

To ensure content can easily be found in searches, Anki normalizes the text to a standard form.

But I think @BlackBeans is right here and it’s just iOS messing with your input.

Yep, this seems to happen when viewing the forum post on iOS as well. Maybe changing the font in the card template will help?
