Enter characters with known encoding in Windows

On Windows, how does one directly enter and?

The Unicode code of is A9, and the corresponding decimal number is 169.

The Unicode code of is AE, and the corresponding decimal number is 174.

In word, you can use "insert"-> "symbol" to input. When character encoding is known, we can use another method. Enter the Unicode encoding (for example, A9), stop the cursor at the Unicode encoding, and press Alt + X to convert the Unicode encoding to the corresponding character, for example, A9. Alt + X can also convert the front character of the cursor into the corresponding unicode encoding. Note that the Unicode encoding here is hexadecimal.

In notepad and other text editors (including the cnbook I wrote), press ALT, press 169, and then release alt. However, in this input mode, only characters encoded between and can be entered, that is, single-byte visible characters.

Because we usually do not know the encoding before the characters, these two input methods are rarely used. Using Alt + X to view character encoding may be more common.

I previously wrote unitoy to view Unicode-supported characters in multiple ways.

When I wrote unitoy, I sorted out the names of all Unicode characters at that time, including Chinese names and English names. The English name is from UCD, and some of the Chinese names are translated by myself, which is not necessarily accurate. I sometimes search for the characters I need in this document.
