Description

TextInput capitalizes all letter I's within words when there's an emoji to the left of the characters and you are editing in the middle of a sentence.

See #19389 for more context

Reproducible Demo

When you have an emoji as the last character of your text input and then move the text cursor back (still with emoji as last character) and enter new letters somewhere in the middle of the string. It only capitalizes the letter i. This also happens if you start your text with an emoji, then type some words, then go back in and start editing text; all i's will be capitalized, even in the middle of words.

Can you run react-native info and edit your issue to include these results under the Environment section?

If you believe this information is irrelevant to the reported issue, you may write [skip envinfo] under Environment to let us know.

Facing everywhere in textInput component. I tried adding autoCaptialize = {none} with some of the textInput. It seems to be working. But all the i's letter are caps still.

Is there any way to fix without updating / changing react native version ?

Having this issue too on IOS since updating to RN0.56.

Also when enabling multiline and there is an emoji in the text:

• All letters go all caps sometimes.
• Adding new lines behaves glitchy when there is an emoji and it is out of view.
• Auto correct suggestions also don't match the word being typed sometimes

Upgraded to RN0.57 and the issue is still there.

Anybody get solution for this?

We've received reports about this issue from our users — we're on RN 0.55. It's difficult to reproduce but seems to occur mostly around the letter i which begins to automatically capitalize when editing text or entering a new word between existing words; the shift key starts to have a mind of its own. It's possible to get into a state where all subsequently entered words are capitalized automatically.

To be clear, this is reproducible without any emojis present.

Here is how we have <TextInput> configured:

<TextInput
 multiline
 autoCapitalize="sentences"
 autoCorrect
 spellCheck
 autoGrow
 style={styles.messageInput}
 value={this.state.input}
 placeholder={inputPlaceholderText}
 onChangeText={input => this.setState({ input })}
/>

@petekp Have you seen any progress regarding this issue? Our users have reported it as well, and I can reproduce it by ending a sentence with a period and then a space, and then going back to the middle of some text and typing. Every letter comes out capitalized.

Also on version 0.55, though you may no longer be.

We've had this patch in production for a while; it definitively solved the issue. Patch is relatative to RN 0.57+.
