I recently found Miranda and install it, and I love it. The only missing thing is Hebrew spell checking.
I saw that
this was raised in this thread in the past, and pescuma
asked for the dictionary and sample words, but wasn't answered.
So, here it is, I hope it will help you realize how to add Hebrew spell checking support to Miranda.
I use the
OpenOffice Hebrew dictionary (linked from
here).
A sample word is שלום (Hello) - mistypes might be - שלופ or זלום.
Another sample is ישראל (Israel) - and mistypes might be ישרטל or ישראך.
I'll be more than happy to provide any additional help to solve this.
