#247 Errors in processing of flag diacritics

[sjurum]

There are quite serious errors in the processing of flag diacritics, leading to substantial over-generation for languages where these are used (mainly for circumfixes and other long-distance dependencies.

To reproduce, do:

1. check out GTHOME and set the env variable $GTHOME to point to this dir (see http://giellatekno.uit.no/doc/infra/infraremake/GettingStartedWithTheNewInfra.html for details)
2. check out Plains Cree:

   svn co https://victorio.uit.no/langtech/trunk/langs/crk

3. cd crk
4. ./autogen.sh
5. ./configure --with-hfst
6. make
7. make check

Notice how the yaml tests gt-norm-yamls/V-mihkwaw_gt-norm.yaml and gt-norm-yamls/V-miywasin_gt-norm.yaml do NOT pass for HFST. The same tests DO pass when using the Xerox tools. The difference is only in the handling of the flag diacritics.

Further details can be found in http://giellatekno.uit.no/bugzilla/show_bug.cgi?id=1859.
