You mean Safari (or WebView) on iOS. Chrome on iOS is just using a skinned WebView because Apple's rules don't allow anything else. In other words Safari on iOS shows the same boxes. When and if Apple danes to fix it it will also be fixed on Chrome for iOS. It's possible it's just a font issue. Tried pasting in FB Messenger, iOS Notes, iOS Messages. All of them just show boxes except for 🅆🄷🅈

  It seems like it is both a font issue and a Safari issue. Here’s a screenshot¹ of all the characters in the string along with their Unicode codepoints: http://f.cl.ly/items/2m0S0t3Y471q1X2u0W1u/Screen%20Shot%202014-03-12%20at%201.37.32%20AM.png http://f.cl.ly/items/2m0S0t3Y471q1X2u0W1u/Screen%20Shot%2020... Note that other than U+0020 (SPACE), U+1F146 (SQUARED LATIN CAPITAL LETTER W), U+1F137 (SQUARED LATIN CAPITAL LETTER H), and U+1F148 (SQUARED LATIN CAPITAL LETTER Y), iOS doesn’t have any fonts containing glyphs for any of the characters. (The squared letter characters are covered (on iOS 7 at least) by the fonts Hiragino Kaku Gothic ProN and Hiragino Mincho ProN²). However, for some reason, Safari on iOS is not performing font substitution in this situation and using one of the Hiragino fonts to display them. As you noted, this font substitution seems to be working fine in other iOS apps, as these squared letters are displaying there. As an aside, on iOS 7, it is finally possible to install custom fonts yourself³ via a configuration profile⁴. I’ve installed a few fonts I’ve needed in this way⁵, and while they work perfectly in apps like Pages (for iOS), Safari seems to completely ignore their existence. Even after installing them and rebooting, Safari still shows the entire string as boxes⁶. (Symbola alone has a glyph for every character in the above string, so every character should certainly be displayable). However, copying and pasting the string of boxes into an app like Pages shows all the characters just fine⁷. ―――――― ¹ — Screenshot is of UnicodeChecker (http://earthlingsoft.net/UnicodeChecker/ http://earthlingsoft.net/UnicodeChecker/). ² — http://support.apple.com/kb/HT5878 http://support.apple.com/kb/HT5878 ³ — http://www.saturngod.net/create-custom-font-for-ios-7 http://www.saturngod.net/create-custom-font-for-ios-7 ⁴ — https://developer.apple.com/library/ios/featuredarticles/iPhoneConfigurationProfileRef/Introduction/Introduction.html https://developer.apple.com/library/ios/featuredarticles/iPh... ⁵ — http://f.cl.ly/items/0o360a3t1q2R3E2a2g2b/IMG_0403.jpg http://f.cl.ly/items/0o360a3t1q2R3E2a2g2b/IMG_0403.jpg ⁶ — http://f.cl.ly/items/3f1o1R2F082i3I0B1y1o/IMG_0404.jpg http://f.cl.ly/items/3f1o1R2F082i3I0B1y1o/IMG_0404.jpg ⁷ — http://f.cl.ly/items/3y1J2G0u2u1c0Y1w2Q3Z/IMG_0405.jpg http://f.cl.ly/items/3y1J2G0u2u1c0Y1w2Q3Z/IMG_0405.jpg
