The attachment has a method String>>asAlphaNumeric:mergeUID: with
which one can convert arbitrary names to a string with fixed size,
guaranteed to be unique and without "tricky chars".
Something like a 'speaking UUID'.
'Crop SketchMorphs and Grab Screen Rect to JPG' asAlphaNumeric: 31
mergeUID: 10 'CropSketchMorphsAndG_iOw94jquN6'
'Monticello' asAlphaNumeric: 31 mergeUID: 10
About clashing probability:
For 10000 packages and a UID length of 10 the worst case probability
of having a duplicate name is < 1.4 e-8. Taking into account that many
package names are shorter than 20 chars and do have unique names
themselves it is much smaller.
