=== How to resolve cUrl error (3) bad range in URL position xx ===

'''Problem'''
When using curl to download URLs containing special characters (like `[]`), you may encounter this error:
<pre>
curl: (3) bad range in URL position 33
</pre>

'''Solution'''
Convert special characters to URL-encoded format:

<pre>
# Incorrect example
curl "https://example.com/api?param[0]=value"

# Correct example
curl "https://example.com/api?param%5B0%5D=value"
</pre>

Common URL encoding references:
* `[` becomes `%5B`
* `]` becomes `%5D`
* Space becomes `%20`

'''Explanation'''
* URL specifications require certain special characters to be encoded for use
* Characters like `[]` have special meanings in URLs and can cause parsing errors if used directly
* URL encoding ensures these special characters can be correctly transmitted and parsed

If you're unsure whether encoding is needed, you can use an online URL encoder tool for conversion e.g. [https://www.urlencoder.org/ URL Encode and Decode - Online].
