PTBatcherGUI does not work with $ in filename

[Frederic Da Vitoria]

Windows 10, Hugin 2019.0 Beta 2

I have pictures in the directory c:\Users\FDV_Common\Downloads\$\$$. I optimized my pictures and saved the pto as Pano.pto in the same directoty, but when I try to assemble, I get the following error:
Could not open project file:c:\Users\FDV_Common\Downloads$$$\Pano.pto

Note that the "\" before the $ seem to have been removed.

Using Hugin_sttch_project, the panorama gets assembled correctly

Fixed in repository.

(If you think you covered all special characters, the next user finds the next characters which breaks something ...)

Just for the record, I tried with a folder named &'(-_)=²°+~#{[`^@]}$£%µ,;!§ (those are on the French keyboard) and PTBatcherGUI worked perfectly. So maybe the next character isn't sp close...
