I am getting question marks for some characters in my HTML 5 output. Some of the characters are ≤ and β. These characters are supported in HTML 5. Is there there some reason that they are not converting or being represented correctly in HTML5 output?
What font are they in? Maybe that's the issue when converted to HTML.
They are in Times New Roman, is there a font that will work with these characters?
The Unicode vintage of TNR populates U+2264 and U+03B2, per the Win7 system I run.
The legacy version of it (probably pre Windows XP) probably doesn't.
Of course, with HTML, there's a dependency on the viewing system fonts, and whether the browser there checks for missing codepoints, and does silent substitutions, or just tosses ?s.
I am not sure what you are trying to explain. FrameMaker creates a Responsive HTML5 output. It places the '?' into the html files it generates. I don't if that clarifies anything but it does sounds like you are onto something. Thanks.
Are you actually seeing the question mark characters in the raw HTML (opened in a text editor, not a browser)? If so, then that implies that FM is doing some font conversion when it creates the HTML, if not, then it means that your browser is substituting the codepoint on you.
The questions marks are in the actual HTML files. Is there something that I can do about this font conversion?
How are they added in the FM content to begin with? That might give a clue as to why they are being filtered out.
Alt codes where used. I am not getting this problem on a different computer could it have been the fonts on that system?
You're not getting the issue in the output when using another machine? That definitely indicates a font issue.
Should I make a new post about a font issue? Is there something I can read or look into to try to solve this font issue?
What ALT codes did you use to create the symbols that are misbehaving? I can try duplicating it to see what's going on..
Concur with Jeff that unpopulated codepoints in the font are the most likely explanation.
Are the codes points U+2264 for the ≤ and U+03B2 for the β?
If not, then you have the [further] problem of using an overlay/codepage font. Historically, these characters were rendered by applying the "Symbol" font to code points \xa3 and \x62, but I'd expect the render-fail to show them as £ and b in that case.
