parsefnc with iso-5589-15 doesn't work

[fradev1988]

Hi,

I'm working on a project where is mandatory to use as encoding iso-5589-15 to generate a pdf417 barcode.

I'm calling the bwipjs.toCanvas with the following options: bcid: 'pdf417', text: myText, scaleX: 3, scaleY: 2, columns: 7, eclevel: 4, parsefnc: true

where "myText" is of this form: "^ECI000017" + valueString.

It seems that all the characters that contain a dieresis like ë are not encoding correcty

as example if I try to convert the following world Schaumbërg the result is Schaumbërg.

Moreover also other special chars like the euro symbol are not correctly rapresented. In this case the euro became €
