I don't know a thing about the web but looks like it might be a font issue. Presumably your setup has the monospaced font available for use in codeblocks, but not the regular text one.

On my machine it says "Lato" and "AwesomeFont" are being used, but both served up over Phacility's CDN. What browser are you using? Shouldn't the browser be downloading the font for use?

i attached my saved webpage. The Text isn't existed the source code.

i don't know whether i miss some components or config.

Ah yea my hypothesis doesn't make 100% sense given all the rest of the text in your screenshot. Are there errors on the server?

Could you tell me how to check the server error?
i don't find the errors on server.

you can check this page, it is original phabricator page, it also cannot show in my server.
maybe the remarkup engine cannot work in my server, i don't know how to resolve it.

Bug reports like this are exceedingly resource intensive on the upstream and as stated, we are unlikely to look into for many years if ever. I'd be happy to accept this bug if you can duplicate the bug in a new, clean, environment and completely list out all components needed to reproduce it. Overall as no one else is reporting this, it is likely an environmental issue - so understanding what is unique in your environment vs everywhere else Phabricator is installed is important. Things to look at:

• Check webserver error logs
• Check javascript console logs
• Install Phabricator in a new, clean OS image. (preferably a free OS, or buy us a proper license if you want support)
• Tell us full, complete, every minor detail, steps to reproduce the issue

The Phabricator versions you listed above are also not current. Just a reminder we only take bug reports at HEAD.

I open the debug mode, on console, i found errors:

pcretest -C

PCRE version 8.10 2010-06-25
Compiled with

No UTF-8 support
No Unicode properties support
Newline sequence is LF
\R matches all Unicode newlines
Internal link size = 2
POSIX malloc threshold = 10
Default match limit = 10000000
Default recursion depth limit = 10000000
Match recursion uses stack

Eventually building a setup check is the extent of our support here. You'll have to build/enable UTF-8 support for your system on your own.

Yes, i manually built the pcre, enable utf8 and unicode properties.
this issue was resolved.
thanks.

Great!
