Whitespace contains ASCII white space and the List contains some unicode white space characters

Apart from what’s in our morphology, there are

  1. unknown word-like forms, and
  2. unmatched strings We want to give 1) a match, but let 2) be treated specially by hfst-tokenise -a Unknowns are made of:
    • lower-case ASCII
    • upper-case ASCII
    • select extended latin symbols ASCII digits
    • select symbols
    • Combining diacritics as individual symbols,
    • various symbols from Private area (probably Microsoft), so far:
    • U+F0B7 for “x in box”

Unknowns are tagged ?? and treated specially with hfst-tokenise hfst-tokenise –giella-cg will treat such empty analyses as unknowns, and remove empty analyses from other readings. Empty readings are also legal in CG, they get a default baseform equal to the wordform, but no tag to check, so it’s safer to let hfst-tokenise handle them.

Finally we mark as a token any sequence making up a:
