The replace_emoji() function was not properly handling empty string
replacements due to a falsy check. When replace="" (the default),
the function would skip replacement and return the original emoji
instead of removing it.
Changed the logic from checking "replace is not None" to always
applying str(replace), which correctly handles empty strings and
other edge cases.
Fixes issue where emoji.replace_emoji("Hello 👋", replace="")
would return "Hello 👋" instead of "Hello ".
- Fix replace_emoji() to properly handle empty string replacements
- Add bounds checking for alias processing in demojize()
- Use safe key access for emoji version data in version()
- Prevent IndexError and KeyError on malformed emoji data
Fixes:
- emoji.replace_emoji("Hello 👋", replace="") now returns "Hello "
- demojize() no longer crashes on empty/short aliases
- version() handles missing 'E' key gracefully
