• Are your trouble same as [this][1]? [1]: stackoverflow.com/questions/2145988/… – Miranda Commented Jul 30, 2014 at 17:22
• Well that sucks, you would think UTF-8 support is a minimum requirement, good thing I never used jsPDF, that simply doesn't cut it for most websites. – adeneo Commented Jul 30, 2014 at 17:24

First off: I urge you to stop using jsPDF if it doesn't support Unicode. It's mid 2014, and the lack of support should have meant the death of the project two years ago. But that's just my personal conviction and not part of the answer you're looking for.

If jsPDF only supports ANSI (a 255 character block, rather than ASCII's 127 character block), then you can simply do a regex replace for everything above \xFF:

"lolテスト".replace(/[\u0100-\uFFFF]/g,'');
// gives us "lol"

If you only want to get rid of quotation marks (but leave in potentially jsPDF breaking unicode), you can use the pattern for "just quotation marks" based on where they live in the unicode map:

string.replace(/[\u2018-\u201F\u275B-\u275E]/g, '')

will catch ['‘','’','‚','‛','“','”','„','‟','❛','❜','❝','❞'], although of course what you probably want to do is replace them with the corresponding safe character instead. Good news: just make a replacement array for the list just presented, and work with that.

2017 edit:

ES6 introduced a new pattern for unicode strings in the form of the \u{...} pattern, which can do "any number of hexdigits" inside the curly braces, so a full Unicode 9 compatible regexp would now be:

// we can't use these in a regexp directly, unfortunately
start = `\u{100}`;
end = `\u{10FFF0}`;
searchPattern = new RegExp(`[${start}-${end}]`,`g`);
c = `lolテスト`.replace(searchPattern, ``);

use

$(htmlstring).replace(/[^\x00-\x7F]/g,'')

to remove all non-ascii charakter

(via regex-any-ascii-character)
