Created attachment 472892 [details] Screenshot This post relates to the Marshallese language. When adjusting letter-spacing to display text in a web browser on Safari for Mac and iOS, diacritics shift to the right (see attachment). The issue occurs with the following characters: L̦ (U+004C, U+0326) M̦ (U+004D, U+0326) O̦ (U+004F, U+0326) This issue can be reproduced even with the simple HTML below, and it does not occur on Windows. sample.html <!DOCTYPE html> <head> <meta charset="UTF-8"> <title>Letter Spacing Example</title> <style> .normal-spacing { letter-spacing: normal; } .wide-spacing { letter-spacing: 12px; } </style> </head> <body> <h1 class="normal-spacing">L̦M̦O̦</h1> <h1 class="wide-spacing">L̦M̦O̦</h1> </body> </html> Thank you for your consideration.
