[BUG] Base64 string encoder/decoder may be have an error

[projoy]

Thank you very much for your IT-TOOLS, it's really good!!
When using the "Base64 string encoder/decoder", I encountered a problem.
In the "String to encode" section, when entering Chinese characters, an error occurs.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'Base64 string encoder/decoder'
2. Go to 'String to encode'
3. Enter any Chinese characters, such as "你好"

The page will then display an error, the exception in console as follows:

DOMException: Failed to execute 'btoa' on 'Window': The string to be encoded contains characters outside of the Latin1 range.
