Common Mistakes to Avoid

⚠️

Uppercase vowels not replaced

Solution: Check if both A and a, E and e, etc. are replaced. Some tools only handle lowercase.

⚠️

Y not included

Solution: Y is sometimes a vowel but usually not replaced by this tool. Handle Y separately if needed.

⚠️

Replacement too long

Solution: Replacing vowels with multi-char strings changes text length. May affect formatting.
