Error reading SymbolTable about openfst

[kkm000]

SplitString uses strpbrk, which treats the string as a set of separator characters, such that any of them is treated as a separator. Given it worked with your change (which is to treat spaces only are separators), then separator is set to a string not containing the space among accepted separators. Check what you pass in SymbolTableTextOptions to SplitString (or, if the error is from an fst* binary, what is passed with the --fst_field_separator switch). By default, both space and tab characters are accepted; this switch is rarely used. I'd hazard a guess the string was somehow set to empty, or maybe to a tab only, but your file has spaces between words and labels.

If this is from command line and you do use the switch, keep in mind that quoting might be tricky in Windows batch files.

FWIW, I do not think Kaldi scripts ever use this switch to fstcompile.

Thanks for the hint. I found that I've committed a careless mistake. Sorry to bother you!

No biggie, you are welcome!
