Doc #63991 [Fbk->Asn]: Accents on uppercase Greek vowels hidden by PHP.net's fonts

Edit report at https://bugs.php.net/bug.php?id=63991&edit=1 ID: 63991 User updated by: php at hatzidakis dot org Reported by: php at hatzidakis dot org Summary: Accents on uppercase Greek vowels hidden by PHP.net's fonts -Status: Feedback +Status: Assigned Type: Documentation Problem Package: Website problem Operating System: Windows 7 Ultimate 64bit PHP Version: Irrelevant Assigned To: aharvey Block user comment: N Private report: N New Comment: It looks OK on the beta site, as that one uses the Monospace font-family. The accents are visible as expected. Previous Comments: ------------------------------------------------------------------------ [2013-01-16 01:40:25] aharvey@php.net Does this happen on the beta site: http://au1.php.net/manual/en/function.mb-convert-case.php?beta=1 ? We could just reuse the code styling from there as a stopgap if it's OK. Since I wrote the original example (bug #51858), the reasoning was that Greek was a non-Latin alphabet that virtually everyone has font support for: I'd rather fix the font issue than switch to something in, say, Cyrillic. ------------------------------------------------------------------------ [2013-01-15 13:59:41] php at hatzidakis dot org 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 this bug report at https://bugs.php.net/bug.php?id=63991&edit=1
