I was planning on starting this series next week, but a quick post idea occurred to me.
Many genea-bloggers have ancestors from foreign countries which often use foreign characters in their character sets. You may know how to draw those characters in your own handwritten notes, and may even be able to get your word processor to reproduce them. However, you may not know how to blog them.
Here's a cheat-sheet.
In the first column you will see what the character looks like. The last column is a description of the character. The middle three columns provide three different codes you can use: "Friendly", Numerical, and Hex. Not every character has a 'friendly' code, which are easier to remember, but they all have the other two. [Note: link above updated from original link to a source with a more complete list]
á is a "lowercase a acute". It is reproduced by typing: á (where that first character is an ampersand.) or á or á
