Firefox ကို ဇော်ဂျီ နဲ့ သုံးမရတာနဲ့ ချက်ခြင်း firefox ရဲ့ bugzilla မှာ report တင်ခဲ့ပါတယ်။
Jonathan Kew က ဒီလို ပြန်ဖြေထားပါတယ်။
The issue here is that the Zawgyi-One font lacks proper layout tables for Myanmar. When loading fonts for “complex” scripts (that require appropriate glyph shaping for correct rendering), Firefox on OS X checks whether the font has the necessary tables, and if not, it will skip it and fall back to a different font.
This font is apparently using the Unicode Myanmar codepoints, but is designed to be used -without- proper shaping support, by instead encoding the text in a “visual” way rather than properly following the Unicode standard for representing Myanmar text.
We’re not going to invest time in trying to support hacks like this. There is a Unicode standard for Myanmar, and an increasing number of fonts that support it. That’s what people should be using for interoperable Myanmar text on the web.
(One other thing: I notice that this font appears to be based on a hacked version of Microsoft’s Tahoma; as such, I suspect that it is in breach of the Tahoma license terms.
