After pressing shortcut

encode decode

Operation to be performed after pressing the above shortcut key

Decode Output Format

Add spaces when outputting non-plain text

Set the output format after Base64 decoding。
If the character encoding is set to GB2312, this setting is invalid。
Add space：\u5728\u4F7F\u7528 → \u5728 \u4F7F \u7528

Encode Input Format

Text H {...}

Set the input format for Base64 encoding。
If the character encoding is set to GB2312, this setting is invalid。

Encode Output Format

Plain Text URL encode

Set the output format after Base64 encoding, where URL encoding is done using the encodeURIComponent function

Encode Symbol Replacement

Replace + with

Replace / with

Replace = with

Also replace when decoding

Replace special symbols (+, /, =) in the encoding result with other content。
Also replace when decoding: Before decoding, first reverse the above checked replacement rules on the text to be decoded。
