Steps/Code to Reproduce

wordcloud = WordCloud(max_font_size=300, background_color = 'white', relative_scaling=1, width=1500, height=1000, colormap='plasma').generate(string1)#generate_from_frequencies(linklist) plt.figure() plt.imshow(wordcloud, interpolation="bilinear") plt.axis("off") plt.show()

Produces the cloud as attached. https://stackoverflow.com/questions/50080183/word-cloud-or-visualization-in-foreign-languages

See discussion in #315 and #238

Yes looks like there is no whole lot of support for Nepali language.

Using popular fonts like Preeti, Kantipur, etc, still generates squares or blocks. However I used Devnagari font available, it kinda generated some but cannot find a full solution to Nepali language. (see partial solution below)

[amueller]

have you tried noto? And what's the problem you're currently facing?

[kneupaneRecordedBooks]

yes, it print the the letters but not printing the words correctly. Wordcloud does not make whole lot of sense.

for an instance,

is not expected from this text

"""हिन्दू धर्मगुरु आचार्य श्रीनिवास पक्राउ परेका छन्। आफूले आफैंलाई गोली हान्न लगाएको अभियोगमा मोरङ प्रहरीको टोलीले श्रीनिवासलाई सोमबार काठमाडौंबाट पक्राउ गरेको हो।"""

[amueller]

If you can't give me more details on what the problem is, I won't be able to help you. So you're saying it's not splitting up the string into words correctly? You can provide your own regular expression. See #272 for a discussion on Thai. Also I highly recommend using Python3 for this. If you figure it out, I'd be happy to add more language specific documentation or examples

[kneupaneRecordedBooks]

Your answer to #272 seems me reasonable and infact it is not because of wordcloud. I know for fact. Its the font issue.

[amueller]

Well the current problem doesn't seem to be a font issue but a tokenization issue (I think) but I can't tell because I can't read the language.

[kneupaneRecordedBooks]

so being the first time trying to implement this in my own mother tongue, I totally feel embarrassed about this tokenization. What are the best resources to learn about tokenization for foreign language. I am sure you have been made aware of this fact.

[amueller]

I don't know. Maybe look at https://nlp.stanford.edu/IR-book/ Also: "foreign" is not really the right word to use here. That would imply as opposed to a native language. I think neither your nor my native language is English, so I wouldn't consider other languages foreign (for me English is a foreign language).

[kneupaneRecordedBooks]

yes probably you are right. I should have made it distinct to "Nepali". Yes, English is my second language. :-)

[SilentFlame]

@amueller Is this issue solved for devnagri script.? As by adding fonts too, I'm unable to get the display of words, still getting rectangular boxes.

[amueller]

@SilentFlame that probably means the font doesn't contain the symbols. Try rendering with PIL/pillow directly.

[SilentFlame]

@amueller thanks, I tried with the suggestion above and it works, just that I had to write my own regex for words.

Hello!, i am having trouble using bangla language text in word cloud. It is not tokenizing correctly. It is breaking the complex word and all the vowel signs. I tried CTLK to tokenize but still no luck.

[amueller]

@Shorotshishir you might need a custom regexp. Tokenization is unfortunately beyond the scope of this package. Let me know if you find a solution. spacy might help.

Hello!, i am having trouble using bangla language text in word cloud. It is not tokenizing correctly. It is breaking the complex word and all the vowel signs. I tried CTLK to tokenize but still no luck.

Use a custom regex and Bengali font. You can use something from Omicron Lab. Here's my code, but I am still facing incorrect glyph placement problem.

rgx = r"[\u0980-\u09FF]+"
wordcloud = WordCloud.(font_path=customFontPath',regexp=rgx).generate(text)
plt.imshow(wordcloud,interpolation='bilinear')
plt.axis('off')
plt.show()

@riyadhrazzaq vai, did you solved the glyph placement problem?

[riyadhrazzaq]

@riyadhrazzaq vai, did you solved the glyph placement problem?

I did not.
