Typing in illustrator has an issue when going to the end of the line - when pressing the End key moves the cursor to the end of the line, including the space; therefore typing again will prepend text to the word on the other line.
To reproduce:
- Type a text which is long enough to break on the next line. Let's say, the text will break between "word1 word2"
- Go to the first line.
- Hit End, then x on the keyboard.
+ Expected result: "word1x word2"
+ Actual result: "word1 xword2"
All text editors prdouce the expected result...
