Hi, A new version is available on the web site with a few bug fixes (still swatting V10 upgrade errors) and a couple of changes.
SPFLite will now examine the actual font in use to determine what characters are not defined. You may now choose ANY character you wish to use as a substitute or turn off substitution entirely (not recommended).
The definition of invalid characters for the P'.' Picture class can now be explicitly defined. See Options => General.
Full details as usual are in the Change Log on the web site.
