How to use Convert UTF8 to Latin1
- 1. Paste the UTF-8 text. Type or paste the text you want converted, such as He with an accented e, into the input pane.
- 2. Choose a Separator. Enter the character placed between each output byte, matching the delimiter your target ISO-8859-1 system or file format expects for hex byte values.
- 3. Copy the Latin1 hex bytes. The output pane shows each character's single-byte ISO-8859-1 value in hex, since Latin1 only covers Western European characters and cannot represent everything UTF-8 can.
When to use Convert UTF8 to Latin1
Convert UTF8 to Latin1 produces the single-byte ISO-8859-1 values a legacy European system, older database column or fixed-width protocol still expects. Because Latin1 covers only Western European characters, this is the tool for confirming exactly what a downgrade from UTF-8 will look like byte for byte.
- Preparing text for a legacy database column. An old database column is still declared as latin1 and you need to confirm the byte values a new UTF-8 string will actually store before inserting it.
- Generating test data for a Latin1 file parser. You maintain a parser for a fixed-width file format that assumes ISO-8859-1 encoding and need known-good byte sequences for accented test characters.
- Debugging a mail server's charset conversion. An SMTP relay declares Latin1 in its headers and you want to verify what bytes it will actually send for a message containing accented European names.
