Doc #63991 [NEW]: Accents on uppercase Greek vowels hidden by PHP.net's fonts

From: php at hatzidakis dot org Operating system: Windows 7 Ultimate 64bit PHP version: Irrelevant Package: Website problem Bug Type: Documentation Problem Bug description:Accents on uppercase Greek vowels hidden by PHP.net's fonts Description: ------------ On Firefox, the font Consolas that PHP.net is using within <code> tags such as in code examples, seems to be hiding the accents from uppercase Greek vowels. This issue does not appear on Internet Explorer or Chrome. Tested Firefox versions v15.0 and v17.01 official binaries on Windows 7 64bit and v12 and v18 on Windows XP. Although this is supported by UTF-8, uppercase Greek vowels must not have accents. It is thus important to be able to distinguish whether a sentence in uppercase Greek has accents or not on its vowels. The example #2 given in http://php.net/mb_convert_case: <?php $str = "Τάχιστη αλώπηξ βαφής ψημένη γη, δρασκελίζει υπέρ νωθρού κυνός"; $str = mb_convert_case($str, MB_CASE_UPPER, "UTF-8"); echo $str; // Prints ΤΆΧΙΣΤΗ ΑΛΏΠΗΞ ΒΑΦΉΣ ΨΗΜΈΝΗ ΓΗ, ΔΡΑΣΚΕΛΊΖΕΙ ΥΠΈΡ ΝΩΘΡΟΎ ΚΥΝΌΣ $str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8"); echo $str; // Prints Τάχιστη Αλώπηξ Βαφήσ Ψημένη Γη, Δρασκελίζει Υπέρ Νωθρού Κυνόσ ?> when viewed on Firefox doesn't include the accents on the capitalized vowels that show the function's effect in uppercasing Greek text. This may confuse developers into thinking the function also removes accents when uppercasing Greek vowels. Copying the example text and pasting it into a text editor makes the accents appear as normal. Test script: --------------- Just view example #2 on http://php.net/mb_convert_case or paste and view this simple html file: <html> <head> <title>test</title> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <style type="text/css"> * { font-family: Consolas ; font-size: x-large; } </style> </head> <body> ΤΆΧΙΣΤΗ ΑΛΏΠΗΞ ΒΑΦΉΣ ΨΗΜΈΝΗ ΓΗ, ΔΡΑΣΚΕΛΊΖΕΙ ΥΠΈΡ ΝΩΘΡΟΎ ΚΥΝΌΣ </body> </html> Expected result: ---------------- I expect the display to be: ΤΆΧΙΣΤΗ ΑΛΏΠΗΞ ΒΑΦΉΣ ΨΗΜΈΝΗ ΓΗ, ΔΡΑΣΚΕΛΊΖΕΙ ΥΠΈΡ ΝΩΘΡΟΎ ΚΥΝΌΣ Actual result: -------------- The display is instead: ΤΑΧΙΣΤΗ ΑΛΩΠΗΞ ΒΑΦΗΣ ΨΗΜΕΝΗ ΓΗ, ΔΡΑΣΚΕΛΙΖΕΙ ΥΠΕΡ ΝΩΘΡΟΥ ΚΥΝΟΣ NOTE: this is just how it looks due to the fonts. Copying the text into an editor reveals the hidden accents. -- Edit bug report at https://bugs.php.net/bug.php?id=63991&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63991&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63991&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63991&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63991&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63991&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63991&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63991&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63991&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63991&r=support Expected behavior: https://bugs.php.net/fix.php?id=63991&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63991&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63991&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63991&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63991&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63991&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63991&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63991&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63991&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63991&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63991&r=mysqlcfg
